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.
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.
yes, diode can be used as rectifier diode to convert ac to dc
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.
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
ratio of ac voltage applied across the diode to the ac current flowing through it
You get a violent explosion as the diode vaporizes.

yes, diode can be used as rectifier diode to convert ac to dc
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
AC forward resistance refers to the effective resistance experienced by an alternating current (AC) signal as it passes through a diode in the forward-bias direction. It is influenced by the diode's intrinsic resistance, as well as the capacitance and inductance of the diode. The AC forward resistance can impact the efficiency and performance of the diode in rectifying AC signals.
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.

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.
1.0A RECTIFIER diode used to convert ac power to dc power
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).
