What else can I help you with?
What is two way current called?
Two-way current is called alternating current (AC). In AC, the flow of electric charge periodically reverses direction, unlike direct current (DC) where the flow of electric charge remains in one direction.
Is led a voltage controller or current controller?
An LED is a diode that emits light; diodes allow current to flow only one direction. The voltage applied to the diode attempts to force current to flow in a specific direction. If the voltage polarity is reversed, and current was flowing before (so there was a small voltage drop across the diode), current will cease to flow (assuming the voltage is not too high for the diode to handle), and (almost) all the voltage will be dropped across the diode (a small leakage current may flow, which means some of the voltage will not be dropped across the diode, but this is in the milli or micro range). I would never define a diode as a "voltage controller" or "current controller". It could be either or both, from the above description.
What statement descibes the flow of electic current in an AC circuit?
The flow of electric current in an AC circuit is alternating, it flows one way then the other, with reference to ground.
When discussing electrical current what does DC stands for?
When discussing electrical current, DC stands for Direct Current (a current where the electron flow in the wires goes only one way)
How the current flow through npn?
A; The base must be positive with respect to the emitter this condition will allow collector current to flow from collector to emitter. If the transistor manage to get saturated the current can flow in both direction. as a switch
How are led's powered?
LEDs are powered by direct current (DC) power. They require the voltage and current that they are built for. LEDs are diodes which means that current will only flow one way through them, if you wire up a LED backwards it will not function.
Which way does the current flow in a car?
The current flow is from positive to negative whereas electron flow is from negative to positive.
In a battery using device the current would flow from the Negitive end through say a led light then find its way to the Positive end of the battery completing the transition?
NO. By tradition and usage : current flows from positive to negative. In reality : electrons flow from negative to positive.
What the role of a resistor in an led circuit?
a resister is to RESIST current flow....if the LED gets the full effect of the power supply, the LED will immediately blow out.
Why are led legs different in size?
Current will only flow one way through an LED, so it has a positive leg and a negative leg. One of them is longer to signify which is which (longer is negative). The negative side also has a chamfered edge on the LED itself.
What is a functoin of a resistor?
esistors restrict the flow of electric current, for example a resistor is placed in series with a light-emitting diode (LED) to limit the current passing through the LED.
What is charged by having a one way current flow through it?
A battery is charged by having a DC current flow through it.
What direction does the Erie canal flow?
its a lake there is no current it does FLOW in any way
Why is LED used in place of a bulb in a tester?
we may use a LED in place of a bulb in a tester as LED glows even when there is a small electric current flow through it
What is two way current called?
Two-way current is called alternating current (AC). In AC, the flow of electric charge periodically reverses direction, unlike direct current (DC) where the flow of electric charge remains in one direction.
What is the difference between a diode and an LED?
A diode is a semiconductor device that allows current to flow in one direction only, while an LED (Light Emitting Diode) is a type of diode that emits light when current passes through it. In simpler terms, a diode controls the flow of electricity, while an LED produces light.
In what circuit does the current flow in one direction and then in the opposite direction?
on a three way switch.alternating current.
