in our home most of the electrical appliances can work only on ac supply e.g. tubelights, fan, refrigeratorsand so on.else we can also say that dc supply is costlier then ac for the same amount of power.

Why does Jim use dc supply in oscillator circuits?
Jim use dc supply in oscillator circuits to and ac out put.
Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
What is use of RFC in Hartley oscillator?
it is a radio frequency choke which connects the dc supply to the circuit but isolate the dc supply from the high frequency oscillations generated in the feedback circuit
Why does we use 250ohms with power supply for the instrument calibration?
We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
What AC motor is used in an escalator?
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
Why not use DC power supply in home?
because it provides direct current in home some equipment need alternating current so we can not use dc supply in home
Why does Jim use dc supply in oscillator circuits?
Jim use dc supply in oscillator circuits to and ac out put.
What is the use of a regulator?
ac supply converted with dc supply
What is the use of regulator?
ac supply converted with dc supply
Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
Why you use dc supply in generator protection panel?
The DC supply may supply power to trip breakers, or to power the protective relays.
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.
Do all electrical home appliances use a DC supply and why?
Not all home applications are run exclusively by a dc current, ex: light bulbs Although some applications involve a dc current requirement such as battery chargers, computers and radios.
What supply should be given for making electro magnets... ac or dc?
For a simple electro-magnet use a DC supply.
Why less loss occurs when you use DC supply than AC supply?
There are less loss occurs when we use DC supply than AC supply, because the frequency is zero in DC, so no Inductance & Capacitance exists.And there is no skin effect in the DC systems, so there is low resistance as compared to AC systems.Rac = 1.25*Rdcfrom Arun Kumar SRR
What does filter do in a transformer?
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
What are the applications of variable DC power supply?
variable dc supply are used to get desired amount of dc supply
