HW34#3 – What is the rate at which energy is dissipated in resistor?

歡迎來到Yogi老師解題給你看,今天我要講解的是AP Physics C Electricity and Magnetism的問題

In the figure below, ℰ1 = 2.00 V, ℰ2 = 5.00 V, R1 = 5.00 Ω, R2 = 4.00 Ω, R3 = 2.00 Ω, and both batteries are ideal.

(a) What is the rate at which energy is dissipated in resistor 1?

(b) What is the rate at which energy is dissipated in resistor 2?

(c) What is the rate at which energy is dissipated in resistor 3?

(d) What is the power of battery 1? (Include the sign of the value in your answer. A negative sign indicates absorption of energy and a positive sign indicates an energy output.)

(e) What is the power of battery 2? (Include the sign of the value in your answer. A negative sign indicates absorption of energy and a positive sign indicates an energy output.)
