The Therapy : Shocks Or Electric Current Firing

- Electroconvulsive Therapy Electroconvulsive therapy is shocks or electric current firing in the human brain. This dangerous procedure is usually used to those that already used pharmacotherapy and psychotherapy and didn’t work for them. The treatment is usually used as a last resort for most people, because there is a risk the treatment might not work or it might cause severe side effects. Some side effect the patient might encounter are confusion, memory loss, nauseas, headaches, muscle ache, high blood pressure, high heart rate, or have other heart problems (Electroconvulsive Therapy (ECT), retrieved October 06,2016)....   [tags: Schizophrenia, Bipolar disorder, Illness]

Making an Electric Current in a Wire

- Making an Electric Current in a Wire You can make an electric current in a wire if a wire is at right angles to a magnetic field and the magnetic field is changing. We say that the electric current has been induced. You can change the magnetism by moving the wire past the magnet, or moving the magnet past the wire. It will show up better on a meter if you use a coil of wire. A current is generated only when the magnet is moving. The current stops if the magnet stops moving - even if it is inside the coil....   [tags: Papers]

Magnetic Bearings and Heat

- One of the main problems associated with the design and application of active magnetic bearings is excessive heat. Heat is generated by two primary mechanisms. The first heating source comes from eddy current loss. Eddy currents are electric currents driven within conductors by a dynamic magnetic field located in the conductor. Eddy current loss in a magnetic bearing are caused by the rate of change in the magnetic field. The relative motion creates a rotating flow of current inside the conductor, which leads to efficiency loss....   [tags: electric current, lubrication]

In order to do so, there must be a supply of delocalised electrons. While in a solid state, ionic substances can not conduct electricity as there are no delocalised electrons or free/mobile ions to act as charge carriers.

The Effect of the Amount of Sodium Chloride on the Electric Current During Electrolysis

- The Effect of the Amount of Sodium Chloride on the Electric Current During Electrolysis Background When an electric current passes through sodium chloride solution, chemical reactions take place at both cathode and anode. If one passes through sodium chloride solution, there will be passage of ions moving through this solution. This results in positively charged sodium ions, which have been dissolved into the solution, moving towards the cathode and deposited there. At the same time, negatively charged chloride ions will be moving towards the anode and discharged at the anode....   [tags: Papers]

Internal Resistance Of Thermal Energy

- Introduction: The (e.m.f) is short for Electromotive Force which is defined as the energy delivered by a battery or a cell per coulomb of charge passing through it. Electromotive Force is measured in volts (V). It is important to point out that Electromotive Force is equivalent to the potential difference (p.d.) throughout the terminals of the cell, which happens when there is no current flowing through. Internal Resistance indicates that all batteries or cells lose energy as thermal energy (in the cell itself) as electricity flow through a circuit as the internal resistance inside the cell starts to resist the flow of the current, which results in thermal energy to be wasted....   [tags: Ohm's law, Volt, Electric current]

Understanding Electric Motors

- MOTOR BASICS BASIC COMPONENTS * Armature - Sometimes called a rotor. This is the part that spins. The armature can be either a permanent magnet or an electromagnet. * Stator - This is the part that doesn't move. The rotor spins in the magnetic field contained in the stator. HOW WORKS A MOTOR. The force that that turns the armature comes from the magnetic field of the armature trying to line up with the external magnetic field of the stator. This force is called torque. This torque will cause the armature to turn until its magnetic field is aligned with the external field, but no further....   [tags: physics motor electricity]

Electric Cars Provide a Great Way to Reduce Oil Consumption

- Radioactive Electric Electric cars provide a great way to reduce oil consumption Introduction One of the big contributing factors to oil consumption, and therefore carbon dioxide emissions, is the constant use of cars for travel. Cars use gas derived from oil, one of the three fossil fuels that release carbon dioxide into our environment. Electric cars can be a simple solution to this problem. Since they run on only electricity, or in some cases mostly electricity (for hybrids), they release little to no greenhouse gases....   [tags: greenhouse gases, carbon dioxide ]

- Lincoln Electric's approach to motivate employees The company motivates employees by providing “reward” and “engagement”. Reward is evaluating the employees properly and giving reasonable salary, and are divided into three parts: -Wages based on actual piecework -Year end bonus linked with the profit the company achieves -Guaranteed employment We can see that piecework is a direct indicator of the employees output. In addition, the year end bonus is linked with the profit the company earns. The guaranteed employment provides employees the base line for their life, so they don’t have to be worried about getting fired or searching for other jobs, which makes them more concentrated on their...   [tags: providing reward and engagement]

Two Features of the Photo-Electric Effect

- The photo electric effect, which was first documented by Einstein in 1905, and posited that the energy of liberated electrons is linearly dependent on the frequency of incident photons. This paper investigates this relationship and measures Planck's constant ($4.36\pm 0.04\e{-21}$MeVs), and the work function of the photo diode ($-1.52\pm0.02$V). Another phenomena which is checked is the charging time of the stopping potential voltage. While there was some dependence between stopping voltage and intensity, this effect is mostly systematic....   [tags: Research Analysis]

The History and Production of Hydrogen

- Hydrogen gas was first identified as an element in 1766, by British scientist Henry Cavendish, in an experiment wherein he separated hydrogen gas by reacting zinc metal plates with hydrochloric acid. Cavendish found that when he applied a spark to the resulting hydrogen gas, it yielded water. It wasn’t until some years later that French chemist Antoine Lavoisier gave hydrogen its modern name. The word hydrogen is derived from the Greek words ‘hydro’ and ‘genes’, which translate as ‘born of water.’ In 1800, two English scientists, William Nicholson and Sir Anthony Carlisle, discovered electrolysis....   [tags: electric, gas, energy]
