Step 1

Given: RC time constant (τ) = 0.0900 s Resistance (R) = 0.0450 Ω Using the formula τ = R * C, we can solve for the capacitance (C): 0.0900 = 0.0450 * C C = 0.0900 / 0.0450 C = 2 F Show more…

The duration of a photographic flash is related to an RC time constant, which is 0.0900 μs for a certain camera. (a) If the resistance of the flash lamp is 0.0450 Ω during discharge, determine the size of the capacitor supplying its energy. (b) If the charging resistance is 860 kΩ, determine the time constant for charging the capacitor.
