What is the potential difference across a 10Ω resistor if a current of 2A flows through it?

What is the potential difference across a 10Ω resistor if a current of 2A flows through it?

Correct Answer: 20V

Step 1: Identify the values given in the problem. We have a resistor with a resistance of 10 ohms (Ω) and a current of 2 amperes (A) flowing through it.
Step 2: Recall Ohm's Law, which states that the potential difference (V) across a resistor is equal to the current (I) flowing through it multiplied by the resistance (R) of the resistor. The formula is V = I * R.
Step 3: Substitute the values into the formula. Here, I = 2A and R = 10Ω.
Step 4: Calculate the potential difference. Multiply 2A by 10Ω to get V = 2A * 10Ω.
Step 5: Perform the multiplication. 2 * 10 = 20.
Step 6: Write down the result. The potential difference across the 10Ω resistor is 20 volts (V).
