Question: What is the voltage across a 5 Ω resistor carrying a current of 3 A?

Options:

Correct Answer: 15 V

Solution:

Using Ohm\'s law, V = I * R = 3 A * 5 Ω = 15 V.

What is the voltage across a 5 Ω resistor carrying a current of 3 A?

What is the voltage across a 5 Ω resistor carrying a current of 3 A?

Step 1: Identify the values given in the problem. We have a resistor with a resistance of 5 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. Replace I with 3 A and R with 5 Ω: V = 3 A * 5 Ω.
Step 4: Perform the multiplication. Calculate 3 * 5, which equals 15.
Step 5: Write down the result. The voltage across the resistor is 15 volts (V).
