In the circuit, the total resistance is increased so by ohms law.
r =v/i.

Increases, because in Series Circuit.

Rt = R1 + R2 + R3 + R4.

Series resistance increases and current is same R = r1 + r2 + r3 + r4.

Thank you for explaining the answer.

In a series connection, the total resistance is equal to the sum of all resistors as new resistor is added, resistance increases.

For example : if resistors are 1,2,3 ohms then total resistance is 6 ohms.
If 4 ohms is added then total becomes 10 ohms.

HENCE PROVED.

R1=4ohms; R2=3ohms Since it is connected in series.
R=4+3=7ohms.
Answer is Increases.

In series Rt = R1+R2+R3+R4+ ..

Resistors series connection formula = R1 + R2 + R3 + R4 + .....Rn.
