Question: What is the voltage across a 10Ω resistor carrying a current of 3A? (2022)

Options:

Correct Answer: 30V

Exam Year: 2022

Solution:

Using Ohm\'s law, V = IR = 3A * 10Ω = 30V.

What is the voltage across a 10Ω resistor carrying a current of 3A? (2022)

What is the voltage across a 10Ω resistor carrying a current of 3A? (2022)

Step 1: Identify the values given in the problem. We have a resistor with a resistance of 10 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 = 10Ω.
Step 4: Calculate the voltage. Multiply 3A by 10Ω to get 30V.
Step 5: Conclude that the voltage across the 10Ω resistor is 30 volts.
