Q
Q: If a 10Ω resistor is connected to a 20V battery, what is the power consumed by the resistor? (2023)
Solution:
Power (P) can be calculated using the formula P = V^2 / R. Here, P = 20V^2 / 10Ω = 40W.
Steps: 6
Show Steps
Step 1: Identify the values given in the problem. We have a resistor with a resistance of 10Ω and a battery with a voltage of 20V.
Step 2: Write down the formula for power (P) in terms of voltage (V) and resistance (R). The formula is P = V^2 / R.
Step 3: Substitute the values into the formula. Replace V with 20V and R with 10Ω: P = (20V)^2 / 10Ω.
Step 4: Calculate (20V)^2. This equals 400V^2.
Step 5: Now divide 400V^2 by 10Ω: 400V^2 / 10Ω = 40W.
Step 6: Conclude that the power consumed by the resistor is 40W.
