Question

if 500000 electrons are moved from higher potential to lower potential within 10 seconds and the work done is 500j for this purpose then find total charge current voltage resistance energy and power
​

Answer 1

Answer:

500000/10= current

=50000ampere

So,

Current = 50000ampere

Work=Voltage*charge

500/500000=1/1000=0.001

So,

Voltage=0.001volt

Resistance= V/I=1/1000*50000=1/5*10⁹Ohm

=2*10^-¹⁰Ohm

Energy= i²Rt=25*10⁸*10*10^-¹⁰*2=10^-¹*50=5 Joules

Power=Energy/Time=0.5Watt
