What does AC and DC stand for in the electrical field?
Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.
Current that doesnt reverse direction is called?
direct current
Which type of current involves charge flow in single direction?
A direct current involves change of flow in a single direction.
What do you call current that does not reverse direction?
Direct.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
Flow of the current.
Why electric cooling fans rotate in opposite direction if there is a change in current flow?
Cooling fans use electric motors which operate by magnetism. As the direction of the current flow reverse, the magnetic poles reverse and hence the change in direction.
When flow can reverse its direction regularly it is called?
Alternating Current (AC) reverses its flow constantly, unlike DC (constant current) which flows in one direction only.
What will be the direction of flow of current in inductor circuit without any source?
With no source, there would be NO current flow. However, if a magnet were to be swiped past the inductor, a charge would be *induced* into the inductor, creating a small. The direction of current flow would depend on which way the magnet was swiped. If you reverse: magnet direction, magnet pole, or the winding direction, you will reverse the flow of current in the inductor. Yes, I mean induced, not inducted. To induct is to introduce, and to induce is to persuade.
How do you reverse series wound motor?
a) Change the direction of current flow through the fields DEC
What is zenor and zener diode?
Zenor diode is allow to flow current in forward direction and it can also allow current in reverse direction when the voltage is above the certain value.
How the direction of EMF depends on the direction of current?
Current flow is from positive to negative. Use the left hand rule for finding the north and south poles. Grab the coil in your left hand, with your fingers wrapped around the coil in the direction of the current flow. Your thumb will then point toward the north pole of the coil. Reverse the positive - negative connections to the coil and the north - south poles will change ends. The left hand rule will still be in effect as the current will now be flowing in the reverse direction as it was in the first connection.
Which type of current does not reverse directon?
Direct current does not reverse direction
Voltage is pressure and current is flow what opposes flow?
Reverse current.
Current that does not reverse direction?
direct current
When the flow of a current is aways in one direction?
When the flow of current is aways in one direction it is known as direct current.
How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
What is the relationship between power and current flowing?
Strictly speaking, it's energy flow that has direction -the term 'power' merely describes the rate at which that energy is flowing. Having said that, however, the term 'power flow' is indeed used, but it must be understood that the term is really describing the 'rate at which energy is flowing'. There is no direct relationship between the direction of current and the direction of 'power'. For example, an alternating current is continually changing direction, while the resulting power flow acts continuously in the same direction. The reason for this is that current flow direction cannot be taken in isolation, as it must be considered together with the direction of the potential difference that is causing that current to flow. If we allocate positive and negative symbols to specify the direction of potential difference and current, where (for example) 'positive' defines a clockwise direction around the circuit, then the product of the two positive signs result in a positive direction for power flow direction. If we now reverse the direction of the potential difference and the current, their signs both become negative, and the product of two negatives is a positive -indicating that the power does not reverse direction, but continues in the same direction.
