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 you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .
What value of voltage measure by DMM Vrms or Dc voltage?
Many can measure both - Vrms (AC) or DC voltage.
What device used to increase or decrease DC voltage?
A DC-to-DC converter is the general term for a device that changes DC voltage at one level to another.
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
Can you connect an AC source in series to DC source - then what happens to the current under a steady state condition?
With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.
What is mean by null voltage?
none voltge

What is excitation of a DC motor?
DC Voltage
What is commutation in DC machines?
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
What value of voltage measure by DMM Vrms or Dc voltage?
Many can measure both - Vrms (AC) or DC voltage.
What voltage is DC?
A voltage DC(direct current voltage) is a uni-direction steady voltage. It is the opposite of an analog/alternative voltage which varies in polarity and direction with time.

Do batteries provide a DC voltage or an AC voltage?
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
