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 value for a transformer determines the amount of voltage that is stepped up or down?
For an ideal transformer, the voltage ratio is exactly the same as its turns ratio. So if, for example, there are twice as many turns on the secondary winding as there are on the primary winding, then the secondary voltage will be twice that of the primary and the transformer will be a 'step up' type.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What does a step up transformer increase?
Power is normally transmitted at high voltage through step up/step down transformers to minimize the power losses in the transmission lines (this is one reason anyway). Since power loss is equivalent to the resistance of the conductor times the current squared, stepping up the voltage by a factor of two cuts the transmission losses by a factor of (2^2 = ) 4.
Advantages of current transformer?
A CT allows:heavy currents to be measured using conventional ammeters, andelectrically-isolates the ammeters from high-voltage primary circuits.

How the secondary voltage in transformer is stepped up?
The secondary voltage in a transformer is stepped up by having more turns in the secondary coil compared to the primary coil. This creates a higher electromagnetic induction which leads to a higher output voltage. The ratio of the number of turns in the primary coil to the number of turns in the secondary coil determines the degree of voltage stepping up.
Can 240v tools be converted to 110v?
It would be better if you got a transformer and stepped up the voltage.
What happens to the current if the potential difference is stepped-up in an ideal transformer?
In an ideal transformer, if the voltage is stepped up by a factor of x, then the current is stepped down by a factor of x. The end result is that the power, P=VI, is not changed. Again, this is in the ideal case.
Advantages of ac generators over dc genrators?
The output of an AC generator can be stepped up with a transformer. The high voltage can be more easily transferred over longer distances with higher gauge wire. At the destination, the high voltage can then be stepped back down with another transformer.
Is tranformer used to increase or decrease AC voltage?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
