An electric bulb draws a current of 0.25 A for 20 minutes. Calculate the amount of electric charge that flows through the circuit.

Options

A. 300C
B. 400C
C. 500C
D. 600C

Explanation

To solve the problem of calculating the amount of electric charge that flows through the circuit when an electric bulb draws a current of 0.25 A for 20 minutes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between current, charge, and time**:
The formula to calculate electric charge (Q) is given by:
\[ Q = I \times t \]
where \( Q \) is the electric charge in coulombs (C), \( I \) is the current in amperes (A), and \( t \) is the time in seconds (s).

2. **Convert the time from minutes to seconds**:
We know that 1 minute is equal to 60 seconds. Therefore, to convert 20 minutes into seconds:
\[ t = 20 \text{ minutes} \times 60 \text{ seconds/minute} = 1200 \text{ seconds} \]

3. **Substitute the values into the formula**:
Now that we have the current \( I = 0.25 \, A \) and the time \( t = 1200 \, s \), we can substitute these values into the charge formula:
\[ Q = 0.25 \, A \times 1200 \, s \]

4. **Calculate the electric charge**:
Performing the multiplication:
\[ Q = 0.25 \times 1200 = 300 \, C \]

5. **State the final answer**:
The amount of electric charge that flows through the circuit is:
\[ Q = 300 \, C \]

### Final Answer:
The amount of electric charge that flows through the circuit is **300 Coulombs**.
