Homework Help: physics

Posted by Laurie on Thursday, January 12, 2012 at 10:13pm.

Lasers are used to try to produce controlled fusion reactions. These lasers require brief pulses of energy that are stored in large rooms filled with capacitors. One such room has a capacitance of 64 10-3 F charged to a potential difference of 7 kV.
(a) Given that W = 1/2CΔV2.


J, find the energy stored in the capacitors.

(b) The capacitors are discharged in 10 ns (1.0 10-8 s). What power is produced?

(c) If the capacitors are charged by a generator with a power capacity of 1.5 kW, how many seconds will be required to charge the capacitors?
