Voltage doesn't 'pass through' anything! Voltage is another word for 'potential difference', and is measured between two points in a circuit. For a transformer to work, it's necessary to apply an a.c. voltage across the transformer's primary terminals.

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 type of transformer used in bed lamps?
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
What is a pole transformer?
It is a type of transformer that you usually see hanging from a utility pole that feeds your house. It transforms the high transmission voltage down to the usable voltage that is used in the home.
Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
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 voltage must be passed across a transformer?
A transformer must be connected to an alternating current (AC) supply of the correct voltage.
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 type of transformer decreases the voltage produced by the source.?
step-down transformer
What type of transformer used in bed lamps?
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
Name the type of voltage that can be changed by transformer?
AC
What is the name of the transformer that reduces the voltage?
a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.
What type of transfomer increases the voltage produced by the source?
step- up transformer
What type of device is uses to increase or decrease the voltage of an electric current?
The device is called a "variac' and it is a type of transformer. It has a variable voltage ouput.
What is a pole transformer?
It is a type of transformer that you usually see hanging from a utility pole that feeds your house. It transforms the high transmission voltage down to the usable voltage that is used in the home.
Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
Which type of transformer is used in sonometer?
A sonometer is used to determine the frequency of alternating current. A step down transformer is used for the determination of frequency of A.C. because the voltage of the A.C. mains is 220V, which is dangerous. The step down transformer reduces this voltage to 6 volts.
