Reference no: EM13533880

Capacitors are used in many applications where one needs to supply a short burst of relatively large current. A 180.0-µF capacitor in an electronic flash lamp supplies a burst of current that dissipates 17.5 J of energy (as light and heat) in the lamp.

(a) To what potential difference must the capacitor initially be charged?

V

(b) What is its initial charge?

mC

(c) Approximately what is the resistance of the lamp if the current reaches 5.0% of its original value in 1.1 ms?

?
