Qgg X 2 = 0.53 X 106 farads= 0.53 microfarads Such a condenser will go into a tin case 1.75 in. square by 4 in. deep. 255. Power in Capacity Circuits.—The power in a circuit atany instant is the product of e and i the voltage and the current atthat instant. In a capacity circuit the current leads… … Fig. 246.—Voltage e, current i and power e X i in a capacity circuit. at m and n the voltage and therefore the power are zero; thepower is also zero at instants q and r when the current is zero.Between m and q energy is stored in the condenser while betweenq and n the same energy is given up by the…
