Question

In a series connection, the net potential difference is the sum of all the potential drops in the circuit.

• A. equal to
• B. greater than
• C. lesser than

Answer 1

The correct option is A equal to

In a series connection the net resistance is equal to the sum of all the resistances.
$R=R_1+R_2+R_3.....$
Multiplying the LHS and RHS with current $I$.
$IR=I_1{R}_1+I_2{R}_2+I_3{R}_3.....$

Applying Ohm's law V = IR
$\Rightarrow V=V_1+V_2+V_3.....$
