What do you call A device that increases or decreases voltage in a power line is a?
A transformer can perform this function.
A device that increases the voltage of an alternating current is called?
That's called a transformer.
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.
What device increases or decreases the volt- age of alternating current?
A transformer can step up or step down AC voltage
What device increases the voltage?
watts
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.
What is thermocouple cable?
The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose
What device increases voltage?
a step-up transformer
What is a device that increase or decreases voltage in a power line?
A transformer. A small example is the coil in a motorcar. A transformer, in a power line, only changes voltage in one direction under normal usage. At distribution voltages, about 8360 VAC, the voltage is monitored by a regulator. A regulator either increases or decreases the voltage automatically to insure the desired voltage is steady. This regulated voltage is then fed to Transformers to provide customers with a regulated voltage at the desired voltage.
A device that decreases voltage?
Step down transformer, potentiometer or rheostats can all be used to reduce voltage.
What is avalanche break down in scr?
A: As the reverse voltage is applied to the SCR increases at a certain point the device will start to conduct that is defined as the breakdown voltage for that device
What is mean by thresold voltage?
the device oprates on the minimum voltage. in this voltage is called threshold voltage.
