☑ Electrical Behavior Of Resistor And Light Bulb

The potential versus current behavior for that of a light bulb is predicted to not follow ohms law as light bulbs give off heat and light. An incandescent light bulb contains tungsten which reduces electricity and converts electricity to heat and light.

The filament in a standard incandescent bulb is a type of resistor.

Electrical behavior of resistor and light bulb. The last colored band gives the tolerance of the resistance value. And this isnt even accounting for the 15 v drop across the bulb when it is lit. Why does the light bulb exhibits a more.

Answer to compare and contrast the electrical behavior of the resistor and the light bulb. Even with the full 45 v across a 1 kw resistor you only get 45 ma flowing thru it. A light bulb to uses electrical energy which is supplied to a resistor that gives off heat as well as light.

With two such resistors in parallel you get 45 ma thru each so 9 ma total. All incandescent bulbs are resistors but only a fraction of resistors are bulbs. The voltage across light bulb and the current across the light bulb were measured and manipulated to solve for resistance.

Thats not going to light up a bulb that requires 300 ma for normal brightness. Conclusion the resistor and the light bulb did not have the same electrical behavior. This resistance will be compared with resistance of a resistor to analyze their electrical behaviors.

The resistor is a thin coiled piece of wire made of tungsten because it has the highest. The resistance for the resistor stayed relatively consistent while the resistance of the light bulb was not constant. The value of the resistance for this resistor is 20 103 20 k with a tolerance of 5 1 k.

The resistor had a resistance of about 13996 ohms. It is not expected to have the same linear plot of current versus time that a resistor is characteristic of. If one of the bulbs is then removed from its socket the other one will.

As an example consider a resistor with the colored bands red 2 black 0 orange 3 and gold 5. The resistance of the light bulb changed with each trial because different amounts of energy were leaving the circuit with each increase of voltage through light and heat. The color codes are given in table 1.

The resistance from the light bulb was determined from the graph of voltage versus current. Two identical light bulbs are installed in two sockets connected in parallel and power is then applied to the combination so that both bulbs light.
