Solution:

Using Ohm\'s law, V = IR = 1.5A * 12Ω = 18V.

What is the voltage across a 12Ω resistor carrying a current of 1.5A? (2023)

What is the voltage across a 12Ω resistor carrying a current of 1.5A? (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 1.5 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 = 1.5A and R = 12Ω.
Step 4: Calculate the voltage. Multiply 1.5A by 12Ω to get V = 1.5 * 12.
Step 5: Perform the multiplication. 1.5 * 12 equals 18.
Step 6: State the final answer. The voltage across the 12Ω resistor is 18 volts (V).
