Never heard of a dictator in the electrical trade. Well, I shouldn't say that, there was one journeyman when I was an apprentice.

What is the function of mylar capacitor?
In electronic circuits a capacitor is used to pass AC and block DC.
Can a diode work in ac?
A diode is a "one-way valve" that allows electrical current to flow in only one direction. A diode placed in series between an AC voltage source and a resistive load will allow current to flow through the load in one direction and block the current when the polarity of the AC voltage changes.
Are diodes only used in a dc circuit?
There are lots of diodes - a "diode" is simply a device that has two electrical connections.If you refer specifically to the rectifying diode, it is used to convert AC current to DC current - so, it is used in a circuit that has BOTH AC and DC.
Total opposition to current flow in an AC circuit with both resistance and reactance is called?
Impedance.
What devices can be used to block DC and pass AC?
simple capacitor can do this job (to block dc and pass ac).
How can you block ac current?
You can block AC current by using a filter with a pass-band that is outside the frequency of the AC current.
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
Why do you still use both ac and DC?
Because some appliances work with ac current and some with dc current.
How many things can a multi meter measure?
Resistance Voltage (both AC and DC) Current (both AC and DC)
What are the similarities in AC and DC?
Both AC and DC are current methods in which electrons move along a wire
Which is more useful ac or dc current?
both. it depends on the application.
An inductor is said to block ac but in transformer which is two inductors coupled together how can it allow an ac current?
While it is true that an inductor opposes the flow of an alternating current, it does not necessarily 'block it'. The quantity that opposes the flow of an AC current is the inductor's inductive reactance, expressed in ohms. Inductive reactance is proportional to the frequency of the supply voltage and, at 50 or 60 Hz, the reactance of a transformer's winding is relatively low (although very much higher than its resistance) and, while this acts to limit the amount of current flow, it certainly doesn't act to block that flow.
If 200V AC generator connected to 200V DC generator then what happens?
current flows in both directions, depending on the AC voltage, i.e when ac is higher, current flows to the dc side, and vice versa
Can a diode work in ac?
A diode is a "one-way valve" that allows electrical current to flow in only one direction. A diode placed in series between an AC voltage source and a resistive load will allow current to flow through the load in one direction and block the current when the polarity of the AC voltage changes.
What is the function of mylar capacitor?
In electronic circuits a capacitor is used to pass AC and block DC.
Does a diode block ac or DC?
A diode blocks current flowing in one direction, and passes a current going into the other direction (with a little potential energy loss). DC is a current flowing into one direction all the time. therefore if you put a diode in a dc circuit it will either always block or always let it pass (provided a certain amount of supply voltage). if you have an ac circuit the current alternates (ac=alternating current) most of the cases the current flows half of the time in one direction and half of the time into the other direction. so you will have both cases 50% blocking 50% passing through. so if you put an LED into an ac circuit, no matter what way you put it in you will always see light.
Why does ACDC have a line in the middle of AC and DC?
AC/DC has the dash in the middle because it was named after a sticker on a sewing machine and that sewing machine was both alternating current and direct current.
