Video on Circuits












1) Series Circuit - circuit that has only one current path


Dorling Kindersley Books


Ex 1) Ammeter – Meter that measures Current






Reference Table Equations


a) IT = I1 = I2 = I3 = ...

Total Current
coming from source

Current going
through each resistor.




b) RT = R1 + R2 + R3 + … 




RT = 6.0 ohms



c) VT = V1 + V2 + V3 + ……



d) VT = ITR OR  RT = VT/IT


Find total current (IT)




20. V = IT(6.0 ohms)


IT = 3.3 amps = I1 = I2




Name that Circuit
