Current Voltage Relationship Of An Incandescent Light Bulb

For example a 100 watt bulb will be giving an optimum performance when it gets 100 watt power.

Current voltage relationship of an incandescent light bulb. Incandescent bulbs are manufactured in a wide range of sizes light output and voltage ratings from 1 5 volts to about 300 volts. Which of the following graphs best represents the current voltage relationship of an incandescent light bulb. They require no external regulating equipment have low manufacturing costs and work equally well on either alternating current or direct current. The filament in an incandescent bulb does not have a constant resistance.

See the bulb s brightness depends on the input power. The goal of this experiment is to show the dependency of voltage on current when measured on a light bulb i e. Generic p o wer la w voltage curren t c haracteristic of an incandescen t. More than that and it the bulb will probably get fused but less than that and it will definitel.

This task is suitable as a problem task students can present their hypotheses explaining the non linearity of the current voltage characteristic of a light bulb. Expert answer 100 3 ratings previous. Answer to which of the following graphs best represents the current voltage relationship of an incandescent light bulb.
