What kind of current used in train?
Trains use DC currents! It's predominantly AC now but more dc in the early days. Both still in use. See DC and AC section below article-
Which instrument is suitable for measuring both a.c. and d.c. quantities.?
We use the "MOTOR GENERATOR SET" to convert the DC power to AC power we use DC motor and ac generator in it. It is very efficient way to convert the DC power to AC power.
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What are the similarities in AC and DC?
Both AC and DC are current methods in which electrons move along a wire
Is fan operating in ac voltage?
A fans blades are driven by motors. Since there are both AC and DC motors, fans can be AC or DC. The fans in your computer are DC fans. Your ceiling fans are AC fans. (Thanks for fixing my answer)

How can a radio use both DC and AC?
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.

Can you use AC instead of DC for superposition theorem?
Yes, the theorem still applies for AC.
Is bulb operate on ac or DC?
It can be operated using both AC or DC
Is commutator used for both ac to dc and dc to ac conversion?
Yes
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
Can you use an ac neutral on a coil powered by dc?
A neutral line can carry both AC and DC. Just make sure that the AC or DC is unable to pass through any components connected to the neutral line.
Does a computer use AC or dc power?
Both, in a way. Electronic components, including moth components inside the computer, need DC. However, since the power available in homes or offices is AC, a computer is designed to work with this. A computer has a power supply that internally converts AC to DC.
How ac change to DC?
by the use of inverter we can convert ac to dc.
Common parts of ac and dc generators?
There is not the big different between AC and DC generator and the common part of both of them areRotorStaterFrameMagnetic FieldBarringShaftWinding (Lap or Wave)Cable boxThe big different between both of them is the commutator and split rings which we use to convert DC to AC.
How many things can a multi meter measure?
Resistance Voltage (both AC and DC) Current (both AC and DC)
