An electronic flash unit for a camera contains a capacitor with a capacitance of 890 μF. When the unit is fully charged and ready for operation, the potential difference between the capacitor plates is 330 V. (a) What is the magnitude of the charge on each plate of the fully charged capacitor? (b) Find the energy stored in the "charged-up" flash unit.
Solution 69 P:
Step 1 of 2:-
Here, we have to calculate the magnitude of charge in each plate of the capacitor.
The capacitance is,
The potential difference between the plates is,
We know that,
So, the charge stored in each plate of the capacitor will be 0.293 Coulomb.
