DC volt Ammeter Display

A DC volt ammeter is a device that measures two important electrical values in a DC (Direct Current) circuit:

1. Voltage (Voltmeter): It measures the electrical potential difference, or the "pressure" that pushes the current through the circuit. This is displayed in volts (V).

2. Current (Ammeter): It measures how much electrical charge is flowing through the circuit, displayed in amperes (A) or milliamperes (mA).

Simple Features:

• Displays Voltage and Current: It shows both the voltage and current on a digital screen.
• Two Functions in One: You can measure both voltage and current in the same device, but it may require switching between the two or have separate displays.
• Easy to Read: Typically has a digital display that shows numbers clearly, making it easy to monitor the circuit.                                                                                               

  Range and Precision:

  • DC volt ammeters typically have a specified range, for example:
    • Voltage might range from 0-30V or 0-100V.
    • Current might range from 0-10A or 0-100A.
  • The precision is usually shown in decimal places (e.g., 12.34V or 5.67A), allowing you to measure both low and high values with accurate readings.

     

  • Power Source:

    • The display itself is powered by the DC circuit under test or an external power source, like a 9V battery or 12V DC adapter.

       

      Voltage Measurement:

      • The display shows the electrical potential difference between two points in the circuit.
      • For example, if you're testing a power supply, the display might show 12.00V or 5.24V depending on the output voltage of the source.
