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?
?
