5.2 Energy storage by capacitors Flashcards
1
Q
When calculating the work done in charging capacitors why can’t we use the normal work done equation
A
potential difference changes as the capacitor charges
2
Q
V is proportional to Q. what does this mean for the average p.d compared to the final p.d
A
The average p.d is exactly half of the final p.d
3
Q
What is the equation for energy transferred when charging a capacitor
A
W = VaverageQ = 1/2VmaxQ
4
Q
What does the capacitor store transferred energy as
A
electric potential energy
