Understanding Electric Current and Charge
Electric current (I) is defined as the flow of electric charge (Q) over time (t). The relationship between charge, current, and time can be expressed with the formula:
Q = I × t
Where:
- Q is the charge in coulombs (C)
- I is the current in amperes (A)
- t is the time in seconds (s)
Given Values
- Current (I) = 0.5 A
- Time (t) = 2 hours = 2 × 60 minutes × 60 seconds = 7200 seconds
Calculating Charge
Now, substituting the given values into the formula:
- Q = I × t
- Q = 0.5 A × 7200 s
Calculation Steps
- First, calculate 0.5 A × 7200 s:
- Q = 0.5 × 7200 = 3600 C
Conclusion
The total charge that passes through the 60 W bulb carrying a current of 0.5 A in 2 hours is 3600 coulombs, which corresponds to option 'A'.
This calculation illustrates how current and time work together to determine the amount of charge flowing through a circuit.
