How long does it take for the current in an RL circuit with R = 130 W and L = 63 mH to reach half its final value?
RL Circuits The current in the RL circuit shown below reaches half its maximum value in 1.75 ms after the switch S1 is thrown. Determine (a) the time constant of the circuit and (b) the resistance of the circuit if L = 250 mH.
The circuit has R = 7.60 Ω, L = 2.20 mH, and C = 1.80 µF. Once
the capacitor is fully charged, the switch is placed on the b
position.
a. How much time does it take so that the amplitude of the
current goes down to 30% of its initial value?
b. How much time does it take to reduce the energy to 30% of
its initial value?
