In the same situation, the battery is changed from 10V to 3 V. Is the final charge on the capacitor larger, smaller or the same as it was when we used the 10 V battery? Why?
Question
In the same situation, the battery is changed from 10V to 3 V. Is the final charge on the capacitor larger, smaller or the same as it was when we used the 10 V battery? Why?
Solution
The final charge on the capacitor will be smaller when we use a 3V battery compared to a 10V battery. This is because the charge (Q) on a capacitor is given by the formula Q = CV, where C is the capacitance of the capacitor and V is the voltage of the battery. If the capacitance remains the same and the voltage is reduced, the charge on the capacitor will also reduce.
