H) Series and Parallel Circuits

Why is it a good idea to connect Christmas lights 'in parallel'?
Circuits - Series and Parallel
1) Series circuit - circuit that has only one current path
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 + ……
So RT = 6.0 ohms
c) VT = V1 + V2 + V3 + ……
d) VT = ITRT OR RT = VT/IT
Find the total current (IT)
VT = ITRT
20. V = IT(6.0 ohms)
IT = 3.3 amps = I1 = I2
