You mean ac coil, the secondary coil, of a transformer? Then for the purpose of rectification, that is , for changing ac into dc, a diode is connected in series with the secondary coil of the transformer.

What happens when you connect 230V ac supply directly to a diode with the help of resistor of the order kilo ohms?
When you connect 230V ac supply directly to a diode with the help of resistor of the order kilo ohms, the diode will conduct on alternate half cycles. Forward bias current will be 230ma for 1KOhm, or 23ma for 10KOhm. Power across the resitor will be 25W for 1KOhm, or 2.5W for 10KOhm. Bottom line - the resistor will get very hot - and if not rated correctly, will be destroyed.
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
How do you find the ac resistance of a diode?
The ac resistance of a diode is found using the equation: (The change in Vd)/(The change in Id) An easier was is to use the Equation: 26mV / Id. This is a general form as the ac resistance of a diode change as the temperature changes.
How does the ac resistance of a diode change as the voltage increases?
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
What are the roles of a diode and a capacitor in an AC-DC converter?
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
What is ac resistance of a diode?
ratio of ac voltage applied across the diode to the ac current flowing through it
What happens when you connect 230V ac supply directly to a diode?
You get a violent explosion as the diode vaporizes.

Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
Can led works as ac sources?
No. An LED (light emitting diode) allows current to flow in one direction, thus it cannot alternate as is implied by "an AC source". ANSWER: YES they can. Any diode can work with AC They can work from AC line directly. My overhead light in my kitchen are across 120 AC now for 8 years. But then again I know what I am doing
What is the Difference between moving coil and moving iron meter?
moving coils will only respond to dc current moving iron will respond to both ac and dc current moving Ion meters tend to be read on a logarithmic scale, are slightly cheaper to manufacture, and are less accurately read. moving coil meters are read on a linear scale, and are more accurate to read. To read AC it must have a capacitor across its terminals and a diode in series to read AC.

How does pn junction diode can be used as an electronic switch?
A diode allows current to flow in only one direction. If the current is flowing, the diode has a low resistance and it behaves like a wire or a switch in the on position. If the voltage across the diode is reversed, no current flows and the diode has a very high resistance. It behaves like a switch in the off position. DC voltages are used to switch the diode on or off. The signal that is being switched is usually an AC audio or radio signal. Capacitors block DC but pass AC signals. By combining diodes and capacitors, the AC and DC signals are kept separate and the switch can be built.
What is N4001 diode?
1.0A RECTIFIER diode used to convert ac power to dc power
How diode convert pure ac to pure dc?
You can't convert ac to pure dc with diode only. The easiest way to convert ac to dc by with diode is by using rectification, it consist of at least 2 diodes (half wave rectifier) and (capacitor is to "smoother" the wave).
What device changes ac to dc in an alternator?
diode
How can display voltage current characteristics on a cathode ray tube?
-- Connect a diode and small resistor in series across a source of AC. -- Using the point where the diode and resistor meet as a common point, connect one scope probe (H or V) to the far end of the resistor, and the other scope probe to the far end of the diode. -- One dimension of the scope display now corresponds to the voltage across the diode. -- Since the voltage across the resistor corresponds to the current through it, the other dimension of the display corresponds to the diode current. -- I leave you to work out the scale factor for the current, and the various polarities.
