Find the resistance in the charging circuit

Reference no: EM13274576

A camera's flash uses the energy stored in a 270ÂµF capacitor charged to 170V. The current in the charging circuit is not to exceed 23mA.

A. What's the resistance in the charging circuit?

B. How long do you have to wait between taking flash pictures? Consider that the capacitor is essentially at full charge in 5 time constants.
