What is the output voltage of this simple circuit?
How would you find the output voltage and current


Swap the diode position with the 4k7 resistor and then "merge" the volt drop of the diode into the 10 volt supply. This problem then becomes a 9.3 volt supply feeding two series resistors where the bottom resistor is attached to - 5 volts.

There is 14.3 volts across those resistors and the total resistance is (4.7 + 2.2) kohm. Therefore the current flowing is 2.0725 mA.

This means that the output voltage is -5 volts + (2.2 kohm * 2.0725 mA) = 

-0.4406 volts.
