Document Summary

Resistors: opposes the flow of current r (ohms, ) Inductors: opposes any change in current i (amperes, a) Capacitors: stores energy in form of electrical charge c (farads, f) Capacitors in series: ceq = c1 + c2 + c3. Voltage divider law: helps us calculate the potential between two known resistances. Va = v voltage drop across r1 = v ir1. Kirchoff"s current law (kcl): current flowing into a node = current flowing out i4 = i1 + i2 + i3 example of kvl & kcl lecture 2 pages 2 to 3. We know if two resistors are connected in parallel. Capable of detecting tiny changes in r. Gives the output in terms of a voltage using voltage divider law. Assume that the resistance of r1 is changing. Could be due to change in temperature. If r1 = r2 = r3 = r4 = r. When two arms of the wheatstone bridge are active.
