Q
Q: What is the formula for the average power consumed in an AC circuit with a phase angle φ? (2020)
Solution:
The average power P in an AC circuit is given by P = VI cos(φ), where φ is the phase angle.
Steps: 5
Show Steps
Step 1: Understand that in an AC circuit, power can vary over time due to the alternating current.
Step 2: Recognize that the average power consumed is not just the product of voltage (V) and current (I) because of the phase angle.
Step 3: Identify the phase angle (φ), which shows how much the current and voltage are out of sync.
Step 4: Learn that the formula for average power (P) in an AC circuit is P = VI cos(φ).
Step 5: In this formula, V is the voltage, I is the current, and cos(φ) adjusts the power based on the phase angle.
