Question

Find the energy dissipated by a current of 0.25 A flowing through a heater fir 10 minutes, when a potential difference of 230V is applied.​

Answer 1

Potential difference= work(energy)/charge. here potential difference = 230v, charge= current×time, charge= 0.25×10×60, then charge is 150c , 230=energy/150, energy is 34500joule
