Question

A potential divider circuit is shown in figure. The output voltage V0 is

• A. 4V
• B. 2 mV
• C. 0.5 V
• D. 12 mV

Answer 1

Answer: (C)

0.5 V

Answer 2

Calculate the equivalent resistance $R_{\text{eq}}$:

$R_{\text{eq}} = 4000 \, \Omega$

Calculate the current:

$i = \frac{4}{4000} = \frac{1}{1000} \, \text{A}$

Then,

$V_0 = \frac{1}{1000} \times 500 = 0.5 \, \text{V}$
