Solve for Power, Voltage Drop, Branch Current, and Total Resistance in the following circuit
using the Parallel Organizer. Record your answers in the table below.
Remember, Voltage (E) Remains Constant
Resistance Total is always less than the least (R)
LeŌ to Right
MulƟply (R x I = E) or (I x E = W)
Up to Down
Add (I₁ + I₂ = It) or (P₁ + P₂ = Pt)
Right to LeŌ
Divide (W / E = I) or (E / I =R)
