RC circuit: time current exceeds 50mA in capacitor discharge
Actually, I'm not sure it's correct but this is what I did: q=VC i(t)=(V/R)e^(-t/(RC)) which, due to t=0, simplifies to i(t)=V/R When I plugged in numbers I got .117 A- kcombs

RC circuit: time current exceeds 50mA in capacitor discharge
Homework Statement Suppose a 120 micro-farad capacitor from a camera flash unit retains voltage of 210 V when an unwary student removes it from the camera. If the student accidentally touches the two terminals with his hands, and if the resistance of his body between his hands is 1.8...- kcombs
