Find equivalent resistance in series combination of resistance

1.	Find equivalent resistance in series combination of resistance
Answer» Series Combination The resistors are connected along the same line The current remains same THROUGHOUT Let there be two resistors with potential DIFFERENCES $V_1 \ and \ V_2$ respectively The net potential DIFFERENCE WOULD be $<klux>V</klux> = V_1 + V_2$ From Ohm's Law, V = IR $\longrightarrow IR = IR_1 + IR_2 \\ \\ \longrightarrow IR = I(R_1 + R_2) \\ \\ \longrightarrow R = R_1 + R_2$ For 'n' number of resistors, $R = R_1 + R_2 + \cdots + R_n$
