Question

Consider the given circuit diagram:
A voltmeter connected between points A and C would read

• A. $0V$
• B. $1.2V$
• C. $3V$
• D. $4.8V$

Answer 1

The correct option is C $3V$

$RAC=2112=\frac{2}{2}=1\Omega$

So,

$I=\frac{6}{\text{Reg}}=\frac{6}{1+1}=3A$

Volume reading $=I\times 1$

$=3\times 1$

$V=3V$
