+5V ---- R1 (4kΩ) ----+---- R2 (1kΩ) ---- GND | Vout (1V)
Explanation:
- R1 (4kΩ) and R2 (1kΩ) are connected in series between the 5V supply and ground.
- Vout is taken from the junction between R1 and R2.
- The voltage divider formula:
The voltage divider formula is:
$$V_{out} = V_{in} \times \frac{R_2}{R_1 + R_2}$$
Substituting the values:
$$V_{out} = 5 \times \frac{1}{4 + 1} = 5 \times 0.2 = 1\,V$$
