WebThe formula is heat produced = voltage squared divided by resistance. In the question he found out the heat as 4 joule per second and then as given voltage was equal to 2 volts. …
WebOhm’s Law. Ohm’s law states that for some devices there is a relationship between electric potential difference, current, and resistance. The equation is: I =\dfrac {\Delta V} {R} I = … WebApr 8, 2016 · 1. Power consumer and power dissipated will be different. Power consumed takes into account power supplied to the resistor and the capacitor. Power dissipation is the I^2.R losses due to heat. The power consumption of the capacitor falls on the imaginary axis. Hence we never observe it as heat.
Web(a) For the resistor, P ave = I 0 V 0 / 2, P ave = I 0 V 0 / 2, whereas for (b) the capacitor and (c) the inductor, P ave = 0. P ave = 0.
