I have not measured voltage in several days. Perhaps your question
could be better answered by someone who has.

Why does the voltage reading drop in measuring the potential difference across the capacitors?
Because the capacitor discharges. so voltage across the capacitor decreases.
What range should you set the voltmeter prior to taking a voltage measurement?
Make a guess of what the voltage will be and set the range accordingly. If needed, change the range after measuring the voltage, to get a better reading.
Do you unplug before measuring resistance?
Yes. Measuring resistance involves imposing a small current through a device and measuring the voltage drop. If there were any other source of voltage, the reading would be in error. You could also damage the ohmmeter if there were an external voltage source. You should also take the device out of circuit before measuring it, so as to not bias the results by the resistance of other devices in the circuit. It all depends on the situation, for which you are responsible for evaluating before you start.
When measuring resistance should there be a voltage applied to the resistor?
No, the meter used to make the measurement will be applying whatever voltage to the resistor it needs to make the measurement. Any additional voltage will disturb this, resulting in at least an incorrect reading and at worst damaging or destroying the meter.
Unit for measuring voltage?
volts
What is the difference measuring in volts?
Voltage
What is dc null voltage?
The term, 'null', simply means 'none' -so, 'null voltage' means 'no voltage'.Most bridge circuits require you to achieve a 'null reading' on its measuring instrument, when using the circuit to determine resistance (in the case of the Wheatstone Bridge), etc.
How voltage gets converted into current in an ammeter?
A: It must be be understood that current needs voltage other wise it is zero. An ammeter for DC is always a voltmeter that reads small IR drop to convert that reading into current present. Like an ohmmeter needs volts to read ohm. Both reading are volts it just convert those reading into whatever scale is switch to.
When measuring voltage the probes should be connected in?
can some one please tell me when measuring voltage the probes should be connected to sequence or series?
How does the technique for measuring current with DMM differ from measuring voltage?
current is measured with the meter in series and voltage is measured with the meter in parallel of the load
Units for measuring voltage are known as?
volts
What is a mulitimeter?
A device for measuring voltage, amperage and current.
