PhysicsEasysingle choice

A $24 V$ battery of internal resistance $4 Ω$ is connected to a variable resistance. If the rate of heat production in the resistor is maximum, then the current in the circuit is

Options:

Answer:

Solution:

When $R = r$ (power dissipated is maximum)

$∴ R = 4 Ω$

$∴ I = \frac{V}{R_{n e t}} = \frac{24}{8} = 3 A$
