voltage is applied to the electrodes at both ends of the product such as both ends of vessel. The rate of heating is directly proportional to the square of the electric field strength and electrical conductivity. The most important factor that effectuates the rate of heating is electrical conductivity and its temperature dependence.

Administration helped with the reasoning behind implementing the policy and some hints to phase outs of the computer labs located in the college of business. We found that students believed that the policy is not effective‚ but should be enforced. For faculty‚ some believe that the policy is helpful for learning and welcome laptops in the classroom while others feel

The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the world. Also generation of electrical power by coal based steam power plants or nuclear power plants

while excluding open loops. Direct exchange systems are significantly more efficient and have potentially lower installation costs than closed loop water systems. Copper’s high thermal conductivity contributes to the higher efficiency of the system‚ but heat flow is predominantly limited by the thermal conductivity of the ground‚ not the pipe. The main reasons for the higher efficiency are the elimination of the water pump (which uses electricity)‚ the elimination of the water heat exchanger (which

Transport Phenomenon (Electrical and Thermal) in two allotropic forms of Carbon (Diamond and Graphite) Graphite and Diamond both are formed from carbon (two allotropic forms of carbon). Though they have similar constituent element‚ they differ a lot in their properties. Diamond is a good thermal conductor but a bad electrical conductor‚ while graphite is a bad thermal conductor but a good electrical conductor. This is one example of their property difference. The difference in their properties

Background Electrical resistivity is the measurement of how a material opposes the flow of an electrical current. On the other hand‚ electrical conductivity () is the inverse of resistivity. It is the measurement of how a material accommodates to electrical currents. If temperature changes‚ the resistivity and conductivity will change accordingly. Temperature coefficient of resistivity () is a measure how temperature affects resistivity. We cannot measure resistivity directly-

purpose of Lab 32 was to determine the effect that the concentration of a solue has on the conductivity of an electrolytic solution. If NaCl is added to water to create an electrolytic solution then it will create a stronger electrical current than distilled water because NaCl is a strong electrolyte that can conduct electricity well due to its ability to dissociate into ions. Materials and Methods: In order to test for the effect that the concentration of a solute has on the conductivity of an electrolytic
