A typical measured I-V (current-voltage relation) characteristic of our NDR diode is shown in Fig. 1C. From this measurement, we see that, initially, the current rises sublinearly with the increase in

The term "resistor" refers to a device that acts as a two-terminal passive electrical component that is used to limit or regulate the flow of electric current in electrical circuits. And it also allows us to introduce a controlled amount of resistance into an electrical circuit. The most important and commonly used ...
WebbPower Delivered to a Resistor: Power is the rate of electrical energy per unit time. It is calculated from the square of the voltage divided by the resistance of the resistor and... WebbEnergy in Resistors. If a certain amount of power is dissipated for a given time, then ENERGY is dissipated. Energy (power x time) is measured in Joules and by including time (t) in the power formulae, the energy dissipated by a component or circuit can be calculated. Energy dissipated = Pt or VIt or V2t/R or even I2Rt Joules.
