Question

What is the voltage, V2, in units of Volts, across resistor R2 in the circuit shown below where VS = 4V, R1 = 14 Ohms and R2 = 35 Ohms?

Answer 1

Correct answer:

`\boxed{v_(out)=2,85V}`

Step-by-step explanation:

We can use voltage divider to solve this problem that is defined as the passive linear circuit producing an output voltage
`v_(out)` that is a fraction of its input voltage
`v_(in)`. So we can use the formula:

`v_(out)=(R_(2))/(R_(1)+R_(2))v_(in), \ where \ v_(in)=v_(s)=4V \\ \\ \therefore v_(out)=(35)/(14+35)(4) \\ \\ \therefore v_(out)=2,85V`
