Question 1237
A
V/8
B
V/4
C
V/3
D
V/2
Explanation.

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:

$$V_{a}$$ = $$\frac{R_{a}}{R_{T}}\times V_{T}$$

$$R_{T}$$ = $$1 + \frac{4\times4}{4+4}$$

⇒ $$R_{T}$$ = $$3\Omega$$

$$V_{1}$$ = $$\frac{1}{3}V$$
