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

Ex 2)

a) I_T = I₁ + I₂ + I₃ + ...

For example:

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

(ignore picture above)

Then ...

I_T = 9 amps

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

V_T = V₁ = V₂ = V₃

V_T= 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?
