Question

what happens to the value of current when a number of resistors are connected in series in a circuit ?what would be their equivalent resistance?​

Answer 1

Answer:

when the number of resistors are increased the value of current will also decrease

the equivalent resistance would be R1+R2+R3+...=Req

Answer 2

The equivalent resistance will be the sum of all resistors and the current will remain constant in series combination.

Given:

A number of resistors are connected in series in a circuit

To Find:

What happens to the value of current and what is the equivalent resistance.

Solution:

Let the circuit in series be R1, R2, R3 .... RN.

• In combination of resistors which is in series the current is the same in every part of the circuit or the same current flows through each resistor and in parallel combination of resistors the voltage remains constant.
• Change in the number of circuit will only change the value of total current I = V / R (TOTAL)

The equivalent resistance will be,

R(eq) = R1 + R2 + R3 + R4 + .... + RN.

Therefore, the equivalent resistance will be the sum of all resistors and the current will remain constant in series combination.
