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.

If a step-up transformer is to increase voltage it needs?
A step-up transformer needs more turns on the secondary windings than on the primary windings to increase the voltage.
How do transformers reduce electrical voltage?
This type of transformer is called a Step-Down transformer. All transformers have an input to output ratio. The transformers that increase voltage are called Step-up, and the transformers that protect against surges are called unity gain. The Unity gain transformer has a 1:1 ratio and provide a mechanical way to isolate a source of voltage from a load.
What type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is the different between et up and set down transformer?
the difference between a step up transformer and a step down transformer is that, in a tsep up transformer, the voltage secondary is greater than the primary side but in a step down transformer, the voltage secondary is lesser than the primary side
Step up transformer is used to increase the?
A step up transformer is used to step up an AC voltage
When a step up transformer increase the volteg what does the volteg increase to?
50000
If a step-up transformer is to increase voltage it needs?
A step-up transformer needs more turns on the secondary windings than on the primary windings to increase the voltage.
What statement correctly describes a step up transformer?
increase the amount of voltage
A transformer can only the voltage of an alternating current?
A transformer can only increase or decrease the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
How to increase 115 volts to 220 volts?
You need a step-up transformer.
What are the two basic uses for a transformer?
To increase or decrease electrical voltage- step up or step down.
What is the fuction of the step-up transformer?
Step-Up Transformers increase the primary voltage to a higher voltage, of same frequency.
What are the types of and uses for a transformer?
There are two types of transformers:- 1. Step-up transformer & 2. Step-down transformer. A transformer used to increase the voltage is called Step-up transformer. A transformer used to decrease the voltage is called Step-down transformer. Uses of step-up transformer:- in power supply stations, in picture tubes of TV, computer monitors, halogen lights, etc. Uses of step-down transformer:- in supply of electricity to homes, in the power supply to the low voltage devices like radio, music systems which are run by AC mains.

What is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.
What is used to increase or decrease voltage that enters a house?
A transformer can be used, either a step-up or step-down transformer, to deliver the power at a different voltage from the normal supply voltage.
