Resistive voltage divider

Calculates properties of resistive voltage divider circuit

Example 1: Must calculate the input voltage when output voltage is 500 millivolts using 120 kilo-ohm source and 10 kilo-ohm sink resistorsView example
Example 2: Must calculate the source resistor to have 1 volt output at 100 volt input using 2.2 kilo-ohm sink resistorView example
