## What would happen to a light bulb is the voltage increased but the resistance stayed the same?

Resistance is the opposition to the flow of the current. If the voltage is increased but the resistance stays the same, the light bulb would glow brighter.

## Does voltage or current affect the brightness of a bulb?

The higher the voltage v the higher the current. If the brightness is caused by a flow of electrons through the filament, a higher voltage will–all things being equal– drive more electrons to flow through the filament. So the brightness is a function of both current and voltage, and can be said to depend on both.

## Does increasing voltage increase power?

If there is an increase in voltage, the power will quadruple. If you increase the voltage (or electrical pressure) in a circuit, then the current (flow of electrons) will increase in direct proportion, eg if you double the voltage the current flow will double.

## Can I use a bulb with higher voltage?

You should never use a higher wattage bulb than your application requires because it will damage your equipment or fixture. … – Bulb Shape: Once we were able to find the correct bulb with the right voltage, wattage and base you are almost good to go, this is where the bulb shape comes into play.

IT IS SURPRISING:  Is it true that Thomas Edison invented the light bulb?

## Why does brightness increase with voltage?

The higher the voltage v the higher the current. If the brightness is caused by a flow of electrons through the filament, a higher voltage will–all things being equal– drive more electrons to flow through the filament. So the brightness is a function of both current and voltage, and can be said to depend on both.

## What effect does the voltage have on the current?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

## Does increasing voltage increase LED brightness?

Adjusting the voltage lower or higher will change the brightness, but only because it also changes the current- higher voltage means the current will increase in an LED.
