How do you increase or decrease voltage?

Answer 1

This question makes no sense as written. However, maybe it will help to know that for a given load if you increase voltage the current increases proportionally and if you decrease the voltage the current decreases proportionally. Ohm's Law says Voltage = Current x Resistance.

Answer 2

Ohm's Law is Voltage = Resistance x Current

So if you hold resistance constant, an increase in Voltage increases current by a proportional amount and vice versa if you decrease voltage.

Answer 3

To increase voltage, you can use a step-up transformer, which has more turns on the secondary coil than the primary coil. To decrease voltage, you can use a step-down transformer, which has fewer turns on the secondary coil than the primary coil. Both Transformers operate on the principle of electromagnetic induction to transfer energy between the coils while changing the voltage level.

Answer 4

Transfomers are used to step up or step down voltages. Example is a door bell transformer steps 120 volts AC to 24 volts AC

Answer 5

Increases or decreases in voltage are just that; they are changes in voltages. And changing voltage is the way electronic stuff works.
