Question

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

• A. \( 1.0 \, \text{A} \)
• B. \( 2.0 \, \text{A} \)
• C. \( 0.5 \, \text{A} \)
• D. \( 0.2 \, \text{A} \)

Hint:

Ohm's law is a fundamental relationship between voltage, current, and resistance in a circuit. Make sure to know the units and rearrange the formula accordingly to find the unknown quantity.

Answer 1

The Correct Option is A

We can use Ohm's law to calculate the current: \[ V = IR \] Where: - \( V = 10 \, \text{V} \) is the voltage, - \( I \) is the current, - \( R = 5 \, \Omega \) is the resistance. Rearranging the formula to solve for \( I \): \[ I = \frac{V}{R} = \frac{10}{5} = 2.0 \, \text{A} \] Thus, the current flowing through the resistor is \( 2.0 \, \text{A} \).
