The quantity t1/2=τ ln 2 is called the half-life of an exponential decay, where τ=rc is the time constant in an rc circuit. the current in a discharging rc circuit drops by half whenever t increases by t1/2. for a circuit with "r=1.0 kω and c=4.0 μf, if the current is 6.0 ma at t=4.0 ms", at what time (in ms) will the current be 3.0 ma?
