Question

A 5-ohm resistor is connected to a 10 V battery. Calculate the current flowing through the resistor.

• A. 1.0 A
• B. 2.0 A
• C. 0.5 A
• D. 0.2 A

Hint:

Use Ohm's Law to calculate the current when the voltage and resistance are known: \( I = \frac{V}{R} \).

Answer 1

The Correct Option is B

Using Ohm's Law: \[ V = IR \] Where: - \( V \) is the voltage (10 V), - \( I \) is the current (which we need to find), - \( R \) is the resistance (5 ohms). Rearranging the formula to solve for \( I \): \[ I = \frac{V}{R} \] Substituting the values: \[ I = \frac{10 \, \text{V}}{5 \, \Omega} = 2 \, \text{A} \] Thus, the current flowing through the resistor is \( 2.0 \, \text{A} \).
