transformer bulb brightness
The bulb connected to the input of a step-up transformer is less bright than a similiar bulb connected to its output. Why?

Re: transformer bulb brightness
Because there is more voltage at the output of a step-up transformer than at the input.

Lamp brightness depends on supply voltage. It gets brighter as the voltage increases.
