**Science**

How can the voltage change in relation to current if the resistance is constant. This is suppose to be using Ohm's law. see above.

**science**

Why does the filament glow more brightly as the electric current in a lightbulb is increased? The glow is dependent on two things: Spectral output, and intensity. Current makes the temperature hotter, and so the spectrum is shifted from red to violet, which is more energetic. ...
*March 7, 2007*

**science**

why is there zero current when a light bulb burns out? With the filamnt burned out there is no connection and no connection means no power is going through the wires; thus, no current.
