Question

If a resistor of resistance R is connected across a battery of internal resistance r then output power will be maximum when:


R=1/4 r

R=r

R=2r

R=4r​

Answer 1

Answer:

R=2r is the right answer

Answer 2

Answer:

R=r

Explanation:

output power is not exceed the input power.

maximium current drawn in circuit wher R=r.

so that maximum power theorem states that the power is maximum when R=r.
