Parallel Circuits - Technical MCQs

Q1:

As additional resistors are connected to a parallel circuit, the total resistance will ___.

A increase

B increase by the value of the resistor being connected

C decrease

D remain unchanged

ANS:C - decrease

If an additional resistor is added in a parallel circuit, the total resistance will decrease.
Since, Rt = 1/R1 + 1/R2+.....1/R4.
