Reference no: EM13514162

Capacitors are used in many applications where one needs to supply a short burst of relatively large current. A 130.0-µF capacitor in an electronic flash lamp supplies a burst of current that dissipates 13.0 J of energy (as light and heat) in the lamp.

Approximately what is the resistance of the lamp if the current reaches 5.0% of its original value in 1.8 ms?
