Why is alternating current more effective at long distance travel than direct current?
Transformers increase and decrease voltage as needed. PLATO
A transformer can only the voltage of an alternating current?
A transformer can only increase or decrease the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
What type of device is used to decrease or increase the voltage of an electric current?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
What type of device is used to increase to decrease the voltage of an electric current?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
What type of device is used to increase or decrease the voltage of an electric current-?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
What device is used to increase or decrease the voltage of an alternating current?
A transformer is the device used to increase or decrease the voltage of alternating current (AC) This is done through a process referred to as inducing.It's operation is based on the fact that electricity produces a magnetic field around itself. By placing 2 coils of cable beside each other, the magnetic field of one coil will induce a voltage in the other coil.
Is a device that changes the voltage of an alternating current with little loss of energy?
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
How do you decrease voltage?
Increase resistance
When are electromagnets used to increase or decrease the voltage of electric currents?
Electromagnets are never used to increase or decrease the voltage in a circuit. These magnets in conjunction with a rotating device (an armature) can create a voltage but the do not have any effect on a voltage.
A device that increase the voltage of an alternating current is called a?
That's called a transformer.
What is a device that changes electric current into a different voltage?
Nothing can change electric current to voltage. You can compare "current " to rate of flow, while "voltage" is the energy level. Transformers can be used to increase or decrease the voltages of alternating current as is done from 'street power' to domestic power.
Which component slow down the current in circuit?
An inductive load can cause current to lag voltage in an AC circuit. An increase in resistance will decrease amount of current flow.
