Question: What is the voltage across a 12Ω resistor carrying a current of 3A? (2023)

Options:

Correct Answer: 36V

Exam Year: 2023

Solution:

Using Ohm\'s law, V = IR = 3A * 12Ω = 36V.

What is the voltage across a 12Ω resistor carrying a current of 3A? (2023)

What is the voltage across a 12Ω resistor carrying a current of 3A? (2023)

Step 1: Identify the values given in the problem. We have a resistor with a resistance of 12 ohms (Ω) and a current of 3 amperes (A).
Step 2: Recall Ohm's law, which states that voltage (V) is equal to current (I) multiplied by resistance (R). The formula is V = I * R.
Step 3: Substitute the values into the formula. Here, I = 3A and R = 12Ω.
Step 4: Calculate the voltage. Multiply 3A by 12Ω to get V = 3 * 12.
Step 5: Perform the multiplication. 3 * 12 equals 36.
Step 6: State the final answer. The voltage across the resistor is 36 volts (V).
