The energy from a single flash of light from a small strobe lamp is 0.8 J. The voltage across the lamp is 230 V.
(a) If the flash of light lasts 10 ms, what is the average current flowing through the lamp?
(b) It is likely that the actual current flowing through the lamp while the light is flashing is not constant. Explain why.
(c) Calculate the average power of the lamp.
