"Alternating Current"

 

 

Series or Parallel??

Dorling Kindersley Books

 

2) Parallel Circuit - circuit in which each component has its own circular path back to the source.

Dorling Kindersley Books

 

Ex 2)

 

 

 

 

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

 

For example:

 

If I1 = 2 amps,
I2 = 3 amps
I3 = 4 amps

(ignore picture above)

 

Then ...

 

 

 

IT = 9 amps


 

 

b) The voltage drops across each component in parallel are equal

 

VT  = V1 = V2 = V3

 

VT = Source Voltage

 

 

** Write in the correct voltages


 

 

 

c) V1 = I1R1

 

V2 = I2R2

 

V3 = I3R3  etc.

 

 

 

 

d) Current in 1st & 2nd resistor?

 

e) What’s R3?
