Why voltmeter does not give more accurate reading of voltage?
Answer: Voltmeter is accurate for voltage and ammeter is accurate for current measurement. This is because a high current of the order of few hundreds or thousand amperes cannot be taken directly by any ammeter. The current , sometimes for calibration, is generated by low voltage of 2.5 V or even lower.
How do you use a voltmeter in Proteus?
How to use Voltmeter in Proteus ISIS
- DC Voltmeter is used to measure the voltage difference across any DC component.
- In order to use DC Voltmeter, we need to click on Virtual Instruments Mode, as shown in the figure.
- In Instruments list, we have DC voltmeter, so click it and place it in your Proteus workspace.
Why voltmeter is not used?
A voltmeter cannot be used to measure the emf of a cell because a voltmeter draws some current from the cell. It employs a null method of measuring potential difference, so that when a balance is reached and the reading is being taken, no current is drawn from the source to be measured.

Why does Proteus not show logic level indicator?
This is because you are using a logic toggle part. This cannot provide any current in the simulation, it is literally a logic level. If you go to the debugging tools section on the parts list (where you got the logic toggle part from) you can also select a logic level indicator, which will go to a 1 or a 0 depending on logic level.
How to set up a real led in Proteus?
If you go to the debugging tools section on the parts list (where you got the logic toggle part from) you can also select a logic level indicator, which will go to a 1 or a 0 depending on logic level. For an LED to work, you would need to set it up as a real circuit, with a voltage input, switches and resistors.
