Parallel Circuits - Technical MCQs

Q1:

What would these meter readings indicate about the circuit in the given circuit?Meter Readings: I = 10 mA, V = 12 V

A <div class="flex-wrap"><i>R</i><sub>1</sub> is open.</div>

B R2 is open.

C The fuse is open.

D The circuit is operating normally.

ANS:D - The circuit is operating normally.

Here, v=12v, r1=7.5 ohm, r2=5 ohm, r3=2 ohm.

WKT,
I=V/R.
I1=V/R1=12/7.5=1.6 mA.
I2=V/R2=12/5=2.4 mA.
I3=V/R3=12/2=6 mA.
Itot=10 mA.

So the ckt is operate normally.
