What device increases the voltage?
watts
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 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.
A device that increases the voltage of an alternating current is called?
That's called a transformer.
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 do you call A device that increases or decreases voltage in a power line is a?
A transformer can perform this function.
What device increases or decreases the volt- age of alternating current?
A transformer can step up or step down AC voltage
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 a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
How is the induced voltage of separately excited dc generator affected if the speed increases?
as speed increases, induced voltage increases
How does the ac resistance of a diode change as the voltage increases?
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
Is voltage decrease with turns?
no,the voltage increases with no. of turns
