Question

a battery of 10V carries 20,000 C of charge through a resistance of
20 ohms the work done in 10 secs is?

Workdone by current flowing through the resistor in time t=I2R t,  where i, r and t are current, resistance and time during which current flows through the circuit
Current through the circuit,  I=VR,  where V=10V, andR=20 ohm
 Therefore,I=1020=0 5 A
  Now workdone by this current in 10 second,W=I2R t=0
52×20×10=0 25×200=50 J
