Question

19. Internal resistance of a 12 V car
battery is 0.02 2. What is the
theoretical maximum power
which it can deliver?
(a) 3600 W
(b) 2400 W
(C) 100 W
(d) 1200 W​

Answer 1

Answer:

a)3600 W

Explanation:

According to maximum power transfer theorem, maximum power can be transferred when the external load is equal to the internal resistance of the source.

So the load resistance should be 0.02 ohm for this condition to be satisfied.

Now the power generated is P = V^2/R

Here R = 2*0.02 = 0.04

Then P = 12^2/0.04 = 3600 W
