Series Circuits - Engineering

Q1:

When a fourth resistor is connected in series with three resistors, the total resistance

A increases by one-fourth

B increases

C decreases

D remains the same

ANS:B - increases

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.
