Question

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

• A. \( 2.0 \, \text{A} \)
• B. \( 1.0 \, \text{A} \)
• 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

Given:

• Resistance: \( R = 5 \, \Omega \)
• Voltage: \( V = 10 \, \text{V} \)

Step 1: Use Ohm's Law to calculate the current

Ohm's law is given by: \[ I = \frac{V}{R} \] where: - \( I \) is the current, - \( V \) is the voltage, - \( R \) is the resistance.

Step 2: Substitute the given values into the formula

\[ I = \frac{10 \, \text{V}}{5 \, \Omega} = 2 \, \text{A} \]

✅ Final Answer:

The current flowing through the resistor is \( \boxed{2.0 \, \text{A}} \).
