Lab: RC Circuits o RC Circuits (circuits with resistor and a capacitor in series) o Current flows only while the capacitor charges up. The time to charge up depends on the product RC. Can also discharge the capacitor C R

Loop Rule (voltage) o The sum of all voltages around any closed loop is always zero. (what goes up must come down) o or V A,A = 0 o !!must keep track of ups and downs!! (+/-) o Across capacitors, resistors, and batteries

Kirchhoff’s Rules, Junction o The sum of all currents at any junction is zero. (what goes in must come out) o !!must keep track of ins and outs!! (+/-) o Current only flows into and out of capacitors while charging and discharging. No current after enough time has passed through capacitors.
