What is the resistance of a 60.0 W light bulb in a household circuit roughly?

∙ 11y ago
Power = (voltage)2/Resistance
Resistance = (voltage)2/(Power)
The standard household voltage in North America is 117 V.
Resistance = (117)2/(60) = 228 ohms (rounded)

How is an open circuit different from a short circuit?
I guess you could call them 'reciprocals' in a sense.-- "Open circuit". . . Has a very high resistance. Nominally infinite.. . . No voltage, no matter how high, is high enough to produce any current through the circuit.. . . Current through it is always zero.. . . Household example: a light switch that's open (labeled OFF in that position).-- "Short Circuit". . . Has a very low resistance. Nominally zero.. . . Any voltage, no matter how small, is enough to produce very high current through the circuit.. . . Household example: toddler stuck a paper-clip into the two holes of the outlet.
When using a 60.0 W light bulb in a household circuit what is the resistance?
We assume your household supply is the common 117 volts. Power = V2/R 60 = (117)2/R 60 R = (117)2 R = (117)2/60 = 228 ohms (rounded)
When more light bulbs are added in parallel to a circuit what happens to the total resistance of the circuit?
"http://www.tpub.com/neets/book1/chapter3/1-26.htm" This site explains how to calculate the resistance, but it decreases the resistance when you add more.
In a series circuit when adding light bulbs does the current change?
Yes. The current is inversely proportional to the resistance. I = V / R where I is current, V is voltage, and R is resistance. Adding light bulbs adds resistance. Current is constant throughout a series circuit; it doesn't change no matter what. Voltage changes.
What happens to the resistance in a parallel circuit when more light bulb is added?
Adding anything(yes,even a superconductor) to a any circuit adds resistance, especially devices that are by there very nature high resistors
What could be a source of resistance in a household electric circuit?
Heat
What effect does decreased resistance have on a circuit?
resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.
Why will the current flow be different in a heated rear screen circuit than a side light circuit?
the heated rear screen circuit has a higher resistance compared to the side light circuit

What two circuits one series and one parallel use light bulbs to provide resistance. Both circuits have the same number of light bulbs?
Series circuit gives higher resistance compared to parallel circuit.
How much resistance does a light bulb create if it has a current of 25 mA around it in a 9 V circuit?

Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
What causes burned car light connectors?
A bad connection, or excessive resistance on that circuit.

How does electric resistance affect electric charges?
In an electrical circuit ,, resistance is the force that resists the flow of electricity thru the circuit .. this is used in light bulbs to create the heat and light that we expect from the bulb .. and heat in a toaster fron the resistance in a wire making it hoy enough to cook the surface of the bread

Yes. The current is inversely proportional to the resistance. I = V / R where I is current, V is voltage, and R is resistance. Adding light bulbs adds resistance. Current is constant throughout a series circuit; it doesn't change no matter what. Voltage changes.
