Electric CircuitsElectric Circuits

A set of electrical components

Sources, Resistors, Inductors, Capacitors

11

Voltage: Volts (V)Voltage: Volts (V)

Potential Difference between two points

Always has polarity (+/-)

Measure voltage in parallel

12

Current: Amperes (A)Current: Amperes (A)

The flow of electrical charge through a conductor or circuit element

Current flow requires a continuous path

Measure current in SERIES

13

Series CircuitsSeries Circuits

Elements placed one after another VTotal = VA + VB + VC

IA = IB = IC

14

Parallel CircuitsParallel Circuits

Multiple elements connected to the same node VA = VB = VC

ITotal = IA + IB +IC

Ohm's Circuit LawOhm's Circuit Law

Voltage is equal to current times resistance

• V =I*R• I = V/R• R = V/I
