1.7 A two-resistor voltage divider employing a 2-k2 and a 1-k resistor is connected to a 3-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% manufactur- ing tolerance, what are the extreme output voltages and resistances that can result?
