A capacitor is charged with 9.6nC and has a 120v potential difference between it's terminals. Compute it's capacitance and energy stored in it
the circuit below consists of a d.c supply of e.m.f of 45V and negligible internal resistance and three resistors. two of the resistors have resistances of 1000Ω and 750Ω as shown. the current drawn from the supply is 0.030A. Calculate the resistance of R
