# Physics Virtual Circuits: Power of a Bulb

Not what you're looking for?

I would appreciate some clear understanding for the solutions to the below questions.

1. An ordinary 150-Watt light bulb has a resistance of about 96 ohms.
Suppose you were to connect an 2.0 V battery to such a light bulb. How much current would flow? Determine how much power the bulb would radiate? (probably too little for a person to detect). Use you own calculations for this question. The lab can be used to test your results by comparing a similar model.

2. What if you were to make a circuit with two 150-Watt light bulbs in parallel -- how much current would flow through each bulb? Compare that to the amount of current which would flow through the bulbs if they were connected in series. Which way would create more light?

3. Is there any way of connecting multiple 150-Watt light bulbs to a battery so that you could actually see them glow? How many do you think you would need? How would they have to be connected?
