Capacitor as Energy SourceMediumQuestion 31560
Question
A camera flash uses a capacitor because capacitors can:
- AStore energy indefinitely
- BDeliver large current for a short timeCorrect
- CIncrease voltage
- DAct as resistors
Correct answer
Deliver large current for a short time
Explanation
Capacitors discharge rapidly, delivering high peak current and thus high peak power for the flash — batteries cannot do this safely.
