Parallel Circuits - Technical MCQs

Q1:

If a branch opens in a parallel circuit, the current in the remaining parallel paths will change.

A True

B False

ANS:A - True

 parallel circuit if on branch is open, the voltage and current for the remaining branches will remains same.

For example if voltage is 10 v and R1 is 2 ohms R2 is 5 ohms, than I1 is 5 amp and I2 is 2 amp. Now if R1 is open then the current for R2 is remain 2 amp.
