The negative terminal of the variable power supply is connected to the positive side of the filament, and the positive terminal of the variable supply is connected to the anode. The voltage provided by the anode power supply is also connected to the X-axis of the XY chart recorder. When powered up, the pen will scan horizontally in response to ...

Variable power supply. Procedure. Using a Digital Logic Board (DLB) and variable power supply, construct the circuit shown below. Use a digital multimeter to measure IT, VR1, VR2, & VR3. Remember, unlike measuring voltage, the current measurement is an intrusive measurement. This means that you must temporarily modify the circuit.

A variable regulated power supply, also called a variable bench power supply, is one where you can continuously adjust the output voltage to your requirements. Varying the output of the power supply is the recommended way to test a project after having double checked parts placement against circuit drawings and the parts placement guide.
