Find the rate of dissipation of electrical energy in the battery. Express your answer using two significant figures. Find the rate of dissipation of electrical energy in the external resistor. Express your answer using two significant figures.Explanation / Answer
A)net resistance=5+0.7
=5.7 ohm
so current=V/R
=12/5.7
=2.105 A
so P=2.105*12
=25.26 W
b) P1=i^2R1
=0.7*2.105^2
=3.1 W
c)P2=i^2R2
=5*2.105^2
=22.155 W
