Name device which permits direct current and opposes the flow of alternating current?
A diode does that.
How to find resistance?
-- Apply a small, known voltage between the terminals of the device. -- Measure the current through the device with the voltage applied. -- Calculate the resistance of the device. It's (voltage) divided by (current).
What device has the smallest current in parallel circuit?
The one with the highest resistance (or impedance, if the voltage is not DC).
When are alternating currents commonly used?
The electrical power that the public utility company delivers to you via the wall outlets in your house is supplied in the form of alternating voltage, which produces an alternating current through any device you plug into one of the outlets.
What is stray magnetic field?
Any device that has a motor or transformer generates a strong alternating magnetic field that travels for a good distance. That means any wire near that device can have a AC voltage (stray voltage) induced on it. If that wire eventually gets to an amplifier that stray voltage can be amplified or heard on a speaker or seen as interference on a TV screen. So you have to shield wires that can carry low level signals to prevent this pickup AC voltage. Sometimes even shielding is not enough, and other measures have to be taken.
A device that increase the voltage of an alternating current is called a?
That's called a transformer.
A device that increases the voltage of an alternating current is called?
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.
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 increased 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 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 has the ability to change direct current to alternating current?
It's called an inverter.
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.
What device increases or decreases the volt- age of alternating current?
A transformer can step up or step down AC voltage
What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
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.
