What is the potential difference across a 5Ω resistor carrying a current of 2A? (2023)

What is the potential difference across a 5Ω resistor carrying a current of 2A? (2023)

Step 1: Identify the values given in the problem. We have a resistor with a resistance of 5 ohms (Ω) and a current of 2 amperes (A).
Step 2: Recall Ohm's law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula. Here, I = 2A and R = 5Ω.
Step 4: Calculate the potential difference: V = 2A * 5Ω.
Step 5: Perform the multiplication: 2 * 5 = 10.
Step 6: Conclude that the potential difference across the resistor is 10 volts (V).
