Question 1

What is the formula for average power dissipation in an RLC circuit?

P_avg = I^2 * R
P_avg = (1/2) * I_rms² * R
P_avg = V^2 / R

💡 Hint: Recall the specific parameters for calculating average power.

Question 2

If the resistance in a circuit is increased, what happens to the average power dissipation assuming current remains unchanged?

True
False

💡 Hint: Consider Ohm's Law and how resistance affects power.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a circuit with R = 50 ohms. If the RMS current is reduced from 4 A to 2 A, what is the change in average power dissipation? Show all calculations.

💡 Hint: Revisit the power dissipation formula for calculations.

Challenge 2 Hard

A certain circuit experiences a power dissipation of 200 W at 5 A RMS current. If the resistance is increased by 10 ohms, calculate the new average power dissipation.

💡 Hint: Rebuild the power calculations step by step.
