DC = direct current, it is a steady charge that keeps going the same direction.
AC = Alternating current, it is a charge that changes direction very quickly. The positive and negative keep switching.

Why current is supplied to DC motor?
What supplies a dc motor is not current, but voltage. Current is what flows in the circuit formed by the dc motor and for the charge. That current varies according to the resistance of the circuit.
Is Electrostatic instruments measure ac and dc?
A DC voltmeter can read an electrostatic field's potential since it can measure a non-changing voltage. However, a electrostatic charge is by definition non-moving. When it does move, it becomes a direct current.
What happens to the capacitance fi the charge on the plates of a capacitor is doubled?
The capacitance doesn't depend on the charge stored in it. The capacitor has the same capacitance whether it's charged by a DC and just holding it, or in an AC circuit where the charge on it keeps changing and reversing, or in a box on the shelf connected to nothing and not charged at all.
How galvanometer measures the charge?
A galvanometer is like a small DC motor with a spring to stop it from rotating all the way around. The greater the voltage the stronger = further the "motor" pulls the needle.
What is difference between ac and DC bulb?
we can check the dc with the help of tester give the reasonAnswerThere is no such thing as an 'AC light bulb' and a 'DC light bulb'. A light bulb doesn't care whether it is subjected to AC or to DC.
What kind of charge is a battery charge?
DC Charge
Can we charge a phone with dc current?
Your mobile phone charger already have ac to dc converter , as ac supply can't stored. and you can charge directly with dc supply by maintaing volage of battery and dc source.
What does dc sTANED for?
DC comics is Detective Comics Washington DC is District of columbia DC++ is Direct Connect Dietitians of Canada Dc recordings is Depth Charge
How do you charge a supercapacitor?
use a dc power source. preferably an ac/dc power adapter. any dc power source will do.
Is lightning AC or DC voltage?
Lightning is static electricity. It's a buildup of charge, and it is facilitated by charge separation. In that light, it is DC.
What company is in charge of broadcasting TV?
The FCC in Washington, DC.
How charge lead acid batteries for 6 v DC?
Charge them with a 6 volt battery charger.
What profession can you seek with a misdemeanor drug charge?
Mayor of Washington DC.
Will a dc to dc charger charges a battery bank faster than an ac to dc charger?
No. The speed at which the charger will charge the battery is determined by how many amps the charger outputs.
Why current is supplied to DC motor?
What supplies a dc motor is not current, but voltage. Current is what flows in the circuit formed by the dc motor and for the charge. That current varies according to the resistance of the circuit.
How long does it take to charge a 12 volt DC battery?
approx 6hrs
What does AC-DC conversion and battery charging mean?
The voltage in your house is AC. It is in the form of a sine wave that goes positive and negative 60 times a second. To charge a battery you need DC so you do an AC to DC conversion and then apply the DC to the battery charging circuit that applies the correct charging current to the battery and checks on the state of the charge.
