Question
A car battery is charged by a 12 V supply, and energy stored in it is 7.20×105 J. The charge passed through the battery is
Solution
The energy stored in the battery can be calculated using the formula:
E = QV
where: E is the energy stored in the battery, Q is the charge passed through the battery, and V is the voltage of the supply.
We can rearrange the formula to solve for Q:
Q = E / V
Substituting the given values:
Q = 7.20×10^5 J / 12 V
Q = 60000 C
So, the charge passed through the battery is 60000 Coulombs.
