Find the power dissipated in the 2 Ohm resistor. Determine the currents in the 2 Ohm and 8 Ohm resistors.

Solution

Ohms law

I= V/R

i.e,V=IR

and

Power law

P=VI =V(V/R) =V²/R

P=VI=IR(I)=I²R

Resistors are in parallel combination

13.power dissipated through 2ohms resistor

P=4²(2)=16(2)=32

14.I=V/R=2/2=1A

and 2/8=0.25A
