LIGHT FIXTURES

the only thing i could think of to write for this blog was the dining table light fixture thing. when i flipped on the switch to light the room the lightbulb went on. cool yeah? yeppp :) so now to the physics part. in order for the bulb to light up, an electric circuit must be in place. we can tell that an electric circuit has been established when the charge flows through the filament causing it to light up. the current flows from the power source to the light bulb. we can measure this current in amperes by dividing the charge passing through the surface, q, by the elapsed time, t.
