a) Current is given as I = V/R from the Ohm’s law
Therefore, I = 1A
But, I = ne Avd
vd = I/neA
When the values for the above parameters are substituted, vd = 1/1.6 × 10-4 m/s
The KE = (KE of one electron)(no.of electrons) = 2 × 10-17J
b) Power loss, P = I2R = 6 J/s
P = E/t
E = Pt
t = E/P = 10-17 s
Current electricity which is also known as Electric current can simply be defined as the flow of electric charge that takes place. The charge that usually occurs takes place, with the help of electrons moving through the wire. The charge present can be either ion in an electrolyte or through the ionised gas called plasma.
