Choose appropriate voltage setting based on circuit type (AC or DC). Set voltage range higher than expected maximum voltage. Black lead goes to COM, red lead to V or mA
Device Manager shows USB port power capabilities through Power data section. Power classification ranges from D0 (maximum) to D3 (lowest). USB ports vary by motherboard form factor, with smallest having fewer. Wake-up devices may require D1 or D2 power states
Voltmeter measures voltage between circuit points in parallel. Voltage is potential difference between circuit components. Voltmeters can measure both DC and AC voltages
Voltage is the difference in electric potential between two points. SI unit is volt (V), named after Alessandro Volta. Voltage can be caused by charge buildup or electromotive force. Voltage is a physical scalar quantity
Create new project in Proteus. Select Voltmeter component from Measurement category. Place component on schematic workspace. Configure settings in Properties dialog box. Connect terminals to circuit points
