Q: What is the power consumed by a resistor of 10 ohms carrying a current of 2 A? (2023)
Solution:
Power P = I^2 * R = (2 A)^2 * 10 Ω = 4 * 10 = 40 W.
Steps: 6
Show Steps
Step 1: Identify the values given in the problem. We have a resistor with a resistance of 10 ohms (R = 10 Ω) and a current of 2 amperes (I = 2 A).
Step 2: Use the formula for power consumed by a resistor, which is P = I^2 * R.
Step 3: Substitute the values into the formula. Replace I with 2 A and R with 10 Ω: P = (2 A)^2 * 10 Ω.
Step 4: Calculate (2 A)^2, which is 4 A^2.
Step 5: Multiply 4 A^2 by 10 Ω: 4 * 10 = 40.
Step 6: The power consumed by the resistor is 40 watts (W).
