What else can I help you with?
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.
What devices can be used to block DC and pass AC?
simple capacitor can do this job (to block dc and pass ac).
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.
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.
Can rheostat run on AC current and DC current?
Yes, a rheostat can be used with both AC and DC currents. The rheostat's variable resistor can be adjusted to control the current flowing through a circuit, regardless of whether it is AC or DC.
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

How do you fix the rear AC of a 2000 Ford Expedition when the front AC still works?
The answer to that question depends on what the rear ac is doing or not doing. Both the front and rear ac systems operate from the same compressor. If your front ac works fine and the system has a full charge your problem might be in the expansion block located in the rear of the vehicle. You can find the block behind one of the rear panels. Remove the panel and run the ac system. follow the ac lined that come up from under the vehicle and you will see that both lines run into what looks like an aluminum block. Check the temperature of the lines on both sides of the block. The line that runs to the rear evaporator should be extremely cold. If it is not chances are that you have an expansion block concern and it should be replaced. CHECK THE FAN RELAY FOR THE REAR AIR ALSO CHECK THE CONTROL LOCATED IN THE HEADLINER
