How many `12.5 mu F` capacitors must be connected in parallel to store a charge of 33.0m C with a potential of 110V across the capacitors?

Text Solution

AI Generated Solution

To solve the problem, we need to determine how many capacitors of capacitance \( C = 12.5 \, \mu F \) are required to store a total charge of \( Q = 33.0 \, mC \) at a voltage of \( V = 110 \, V \). ### Step-by-Step Solution: 1. **Understand the relationship between charge, capacitance, and voltage**: The formula relating charge \( Q \), capacitance \( C \), and voltage \( V \) is given by: \[ Q = C \cdot V ...
