Atwo-resistor voltage divider employing a 2-k and a 3-k resistor is connected to a 5-v ground-referenced power supply to provide a 2-v voltage. sketch the circuit. assuming exact-valued resistors, what output voltage (measured to ground) and equivalent output resistance result? if the resistors used are not ideal but have a ±5% manufacturing tolerance, what are the extreme output voltages and resistances that can result?

Rout=1.2K

Vmax=2.12V; Vmin=1.88V

Rmax=1.26K

Rmin=1.14K

Explanation:

You can find the circuit diagram attached.

Seing from the output and with no power supply, the output resistance will be R1 in parallel to R2:

Rout = R1 // R2 = 1.2K

The maximum output voltage will be when R1 = 3K-5%   and R2 = 2K+5%:

Minimum voltage will be when R1 = 3K+5%  and R2 = 2K-5%:

As for the output resistance:

Rmax will be when R1 = 3K+5%  and  R2 = 2K+5%:

Rmax = 1.26K

And Rmin will be when R1 = 3K-5%  and  R2 = 2K-5%:

Rmax = 1.14K
