How current are made?
You cause the current to flow through an electronic device that allows current to flow in one directionbut not in the other direction. Such a device is called a "diode" or a "rectifier".
How do we usually think of voltage as the cause and currents the effect?
You apply a voltage across a load and the result is that a current flows through the load. So you must have the voltage present, the cause, before current flow, the effect. Think of voltage as pressure and current as flow.
The only way to stop a 4 layers diode that is conducting is by?
To cause a Shockley diode to stop conducting, reduce the current going through it to a level below its low-current dropoutthreshold.
An increase in resistance in a circuit will cause?
In a simple circuit, lowering the voltage will not cause the resistance to do anything. Lowering the voltage will, however, cause the current to also lower.This ignores temperature coefficient. If there is substantial power involved, a typical bulb, for instance, will grow cooler and its resistance will decrease when you lower the voltage, but that is usually a small effect.
Which is more dangerous amps or currents?
It depends on your proximity to the circuit under consideration and your electrical relationship to it. If your body is a part of the circuit, and the current happens to flow through or near your heart, then as little as 0.015 Amp can ... as they say ... cause death. If, on the other hand, you are not a part of the circuit and the current does not flow through you, then there is no danger regardless of the magnitude of the current.
What would cause the heater fan rear defroster to not work on a 1991 Chevy caprice the heater fan only works on the highest setting?
If the heater fan on your 1991 Caprice only works on "High" the problem is more than likely the resister assembly in your blower circuit or poor connections at the resister assembly. When the switch is in the "high" position the current does not flow through the resister assembly it flows directly to the coil of the blower relay. When the switch is in "low", "medium 1", or "medium 2" position the current flows through 1, 2, or all 3 of the resistors in the resistor assembly which results in the 3 different lower speeds. Check the resister assembly and replace if needed.
How does voltage cause current to do work?
A voltage will cause electrons or other charge carriers to flow (if there is a path through which they can flow). In other words, it will cause a current.

What does voltage cause?
The ability of current to move through a wire.
How does voltage cause current to work?
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
What must pass through a coil in order to make an electromagnet?
An electrical current will cause an electromagnet to energise.
What if your ballast resistor is bypassed on your 1973 350 Chevy engine Why?
Eliminating the ballast resistor will cause excess current through the coil, and will cause excess current through the points.When that happens, the points and/or coil will fail prematurely.
If the fan only blows on high on a 2002 jeep liberty is the relay switch bad or is it the fan motor?
If the fan only blows on high in the Liberty, check the blower resister. The resister circuit is the most likely cause.
You only have high speed on your heater blower what is wrong 2003 mercury sable?
The most likely problem with the heater blower on your 2003 Sable is the blower resister. The resister can go bad and cause you to only have one speed.
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
How current are made?

How much current would an applied voltage of 10 volts cause through a resistance of 5 ohms?
10 volts applied to 5 ohms would cause a current flow of 2 amperes. Current = voltage divided by resistance.
