Why is it a good idea to connect
Christmas lights 'in parallel'?

Which kind of circuit do we have below?

Series

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

Ex 1) Ammeter – Meter that measures Current

Reference Table Equations

a) I_T = I₁ = I₂ = I₃ = ...

Total Current
coming from source

=

Current going
through each resistor.

b) R_T = R₁ + R₂ + R₃ + ……

R_T = 6.0 ohms

c) V_T = V₁ + V₂ + V₃ + ……

d) V_T = I_TR_T ORR_T= V_T/I_T

Find total current (I_T)

V_T = I_TR_T

20. V = I_T(6.0 ohms)

I_T = 3.3 amps = I₁ = I₂

Name that Circuit
