(a) power = (discharge energy)/duration
= 5000 W
(b) discharge energy = (1/2)*C*V^2
Solve for C
(c) Avg. Power
= (Energy per flash)*(0.1 flashes/sec)
A camera flashtube requires 5.0J of energy per flash. The flash duration is 1.0 ms. (a) what power does the flashtube use while it's flashing? (b)If the flashtube operates at 200V, what capacitance is needed to supply the flash energy? (c) If the flashtube is fired once every 10s, what's the average power consumption?
