A device that increases the voltage of an alternating current is called?
That's called a transformer.
What does the term rectifier mean?
An electrical device that converts alternating current to direct current is known as a rectifier. An inverter is a device that converts direct current to alternating current.
What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
Which device is used to convert direct current into alternating current?
An inverter
Is power transformer is constant current device?
No, it has to be an alternating current in order to work
What is a device used to change voltage of an alternating current?
A transformer.
Name device which permits direct current and opposes the flow of alternating current?
A diode does that.
What device has the ability to change direct current to alternating current?
It's called an inverter.
Which is the device that converts AC to DC?
A Rectifier converts Alternating current into Direct current
A device that increase the voltage of an alternating current is called a?
That's called a transformer.
What do you call A device that increases or decreases voltage in a power line is a?
A transformer can perform this function.
In a series circuit each device that is added to the circuit decreases the what?
Depends on the device. If it is a resistor and you have a fixed voltage then the circuit will obey Ohms law. Voltage = Current x Resistance. So if R increases by adding more resistors in series and the voltage is constant, the current will decrease.
