A capacitor is connected across an ac generator whose frequency is 910 Hz and whose peak output voltage is 170 V. The rms current in the circuit is 2.3 A. (a) What is the capacitance of the capacitor? (b) What is the magnitude of the maximum charge on one plate of the capacitor? Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise. +9. Irms V sin 2n ft (a) Number Units (b) Number i Units
