(b) the power dissipated in each resistor and
(c) the power of each battery, stating whether energy is supplied by or absorbed by it

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
a. `i=(12-6)?(4+8)=0.5A`
b. `P_(R_1)=i^2R_1=1W`
`rarr P_(R_2)=i^2R_2=2W`
c. Power supplied by `E_1=E_1i=6W`
and power consumed by `E_2=E_1i=3W`
