diodes conduct electricity in only one direction but as ac change direction in each of its cycle diodes can only conduct half of its cycle which will give u a pulsating dc. but if dc is mixed with ac and if it can put whole of its cycle in positive direction diode can conduct ac. so diodes are usually used to produce dc from ac.

How does DC to ac power supply work?
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
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.
Where should ac or DC supply be used?
The type of power supply being used (AC or DC) should match the power requirements of the device it will be supplying power to.
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is the function of a zener diode in a dc power supply?
zener diode use as power regulator and it removes the small pics generated while the time of conversion by rectifies supply from AC to Dc...it is compulary to fixed a zener diode with rectifiier circuit for the protection of electronics devices....we all know that all electronics eqiupments arework on DC... on more think zener diode available in the series of 74XX ..i hope u satisfied.. ANSWER: It uses its own controlled breakdown voltage as a regulator since the voltage remains the same while current may go up or down caused by the varying input
