Unformatted text preview: R eq = R 1 + R 2 + R 3 + .... (b) For resistances hooked in parallel: 1 R eq = 1 R 1 + 1 R 2 + 1 R 3 + .... (Dont forget to take the reciprocal to get R EQ . ok? ) 4. Transformer Equation : V P N P = V S N S where: V P , V S , N P , and N S are the voltages and number of turns in the primary and secondary coils. 1...
