Capacitor as Energy SourceMediumQuestion 31560

Question

A camera flash uses a capacitor because capacitors can:
  1. A
    Store energy indefinitely
  2. B
    Deliver large current for a short time
    Correct
  3. C
    Increase voltage
  4. D
    Act 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.
