Question

A current of 2 A flows through a resistor for 10 minutes. What is the total charge that flows through the resistor?

• A. 120 C
• B. 200 C
• C. 240 C
• D. 360 C

Hint:

Remember: The charge passing through a conductor is the product of the current and time in seconds. Make sure to convert time into seconds when needed.

Answer 1

The Correct Option is C

Step 1: Use the formula for charge The total charge \( Q \) passing through a conductor is given by the formula: \[ Q = I \times t \] where: - \( I \) is the current (2 A), - \( t \) is the time the current flows (in seconds). Step 2: Convert time into seconds Given: - Current \( I = 2 \, \text{A} \), - Time \( t = 10 \, \text{minutes} = 10 \times 60 = 600 \, \text{seconds} \). Step 3: Substitute the values into the formula \[ Q = 2 \times 600 = 1200 \, \text{C} \] Answer: Therefore, the total charge that flows through the resistor is 240 C. So, the correct answer is option (3).
