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)

 

VT = ITRT

 

20. V = IT(6.0 ohms)

 

IT = 3.3 amps = I1 = I2

 

 

 

Name that Circuit
