Differential Amplifier

This is a simple differential amplifier, experiment with changing the two DC supplies to change the output.

By default the circuit is doing 10 - 5 = 5 Volts

If you want to amplify the output then change  the two resistors furthest to the right. For example, if you set both of them to 2K, then the output will be doubled.

Here's a tip: use something like 100k resistors. You don't want your differtial amp drawing too much current from the nodes it's connected to.

Take the example of current sensing. If you are trying to measure the voltage difference across a current sense resistor, having low resistance resistors can skew the current reading due to the high current draw of the diff amp resistors.
