In the circuit shown both capacitors are initially charged to 45.0 V. (a) How long after closing the switch S will the potential across each capacitor be reduced to 10.0 V, and (b) what will be the current at tha time? 15.0 20.0 50.0 0 µF FuF 30.0 2

A controller on an electronic arcade game consists of a variable resistor connected across the plates of a 0.220 mF capacitor. The capacitor is charged to 5.00 V, then discharged through the resistor. The time for the potential difference across the plates to decrease to 0.800 V is measured by a clock inside the game. If the range of discharge times that can be handled effectively is from 10.0 ms to 6.00 ms, what should be the (a) lower value and (b) higher value of the resistance range of the resistor?

A 1.5 V battery produces 44.6 mA when it is across a 30.0 0 load. The potential difference across the battery's terminals is_ V. Normal format with 3 SF.
