Answer:
Potential difference across resistor will be 87.66 volt
Explanation:
We have given number of electrons
Charge on one electron
So total charge
Time is given t = 5 min
1 minute = 60 sec
So 5 minute = 5×60 = 300 sec
So current
Resistance is given R = 40 ohm
Sp from ohm's law potential difference across resistor v = iR = 2.1866×40 = 87.466 volt
