V/3 
D
V/2 
Explanation.
Share Answer

Using the voltage- divider method which states that the output voltage is directly proportional to the input voltage and the ratio of R1 and R2, given by:

\(V_{a}\) = \(\frac{R_{a}}{R_{T}}\times V_{T}\)

\(R_{T}\) = \(1 + \frac{4\times4}{4+4}\)

⇒ \(R_{T}\) = \(3\Omega\)

\(V_{1}\) = \(\frac{1}{3}V\)
