What is the power consumed by a 6Ω resistor when a current of 2A flows through it? (2023)
Step 1: Identify the values given in the problem. We have a resistor with a resistance of 6 ohms (Ω) and a current of 2 amperes (A) flowing through it.
Step 2: Recall the formula for power (P) in an electrical circuit, which is P = I²R, where I is the current and R is the resistance.
Step 3: Substitute the values into the formula. Here, I = 2A and R = 6Ω.
Step 4: Calculate I². This means multiplying the current by itself: (2A)² = 2A * 2A = 4A².
Step 5: Now multiply the result from Step 4 by the resistance: 4A² * 6Ω = 24W.
Step 6: The final answer is that the power consumed by the resistor is 24 watts (W).
