1. Electric Circuit

2. SERIES CIRCUIT +- RARA RBRB In this Circuit, electric current has one path to flow (1) The current is same everywhere in the circuit (2) The Voltage of source is the sum of voltage in R A and R B (3) The equivalent resistance is the Total resistance that connected (4) Series Circuit is called voltage divider circuit I Sources = I A = I B ……………..(1) V Sources = V A + V B ……………..(2) R equivalent = R A + R B ………….. (3) I = V source /R equivalent ……… (4)

3. PARALLEL CIRCUIT +- RARA RBRB I Sources = I A + I B …………..(1) V Sources = V A = V B...………..(2) 1/R equi = 1/R A + 1/R B …………..(3) I
