Question

At what rate is thermal energy being generated in the 2r-resistor when ε = 12 V and r = 3.0 Ω?

Answer 1

The rate at which thermal energy is being generated in the 2r-resistor is 12W.

Step-by-step explanation:

To calculate the rate at which thermal energy is being generated in the 2r-resistor, we can use the formula for power, which is P = V^2 / R. Given that ε = 12V and r = 3.0Ω, we can substitute these values into the formula to find the power.

So, P = (12V)^2 / (2 * 3.0Ω) = 12W

Therefore, the thermal energy is being generated at a rate of 12W in the 2r-resistor.
