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.
It depends entirely on the input voltage and the 'turns ratio' between the primaty and secondary coil. If the secondary has twice as many turns as the primary the output is double the input. If the secondary has half the turns of the primary then the output is half the input.
Primary voltage in, secondary voltage out.
You get alternating current, AC, from a transformer.
Its 'secondary voltage'.
Secondary voltage.
The secondary voltage.

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
If the bed lamps use a low voltage bulb then the type of transformer will be a step down 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.
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
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.
A transformer must be connected to an alternating current (AC) supply of the correct voltage.

step-down transformer
If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.
AC
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.
step- up transformer
The device is called a "variac' and it is a type of transformer. It has a variable voltage ouput.
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.
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
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.
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.
