Answer 2

Answer:

In series, the current is constant.

So,

$V = V_{1} + V_{2} + ...$

$IR = IR_{1} + IR_{2} + ...$

Since current is constant, taking it as common we get,

$R_{eff} = R_{1} + R_{2} + ...$    ⇒ This is the expression obtained for effective                                 resistance in series
