Answer 1

here is ur answer...

Answer 2

current= charge/time
potential difference= work done / charge
potential difference= current × resistance
heat = potential difference×current × time
heat = current^2×resistance× time
heat =potential difference^2/resistance × time
Resistance
in series combination
resultant resistance= R1+R2+R3+..
In parallel combination
resultant resistance= 1/R1+1/R2+1/RE+...
power= potential difference×current
power =potential difference^2/resistance
power=current^2×resistance
