Let s say you have a 120 watt light bulb plugged into a wall socket.
0 6 amp light how much resistance 120v wall.
Choose your answer below.
A typical cheap 60 watt equivalent to incandescent led light bulb is advertised as providing 800 lumens lasting up to 10 000 hours at 10 watts.
The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω.
So to double check those numbers i grabbed a dmm switched the range to selector to the ohm symbol and touched the leads to the contacts on the light bulb it finally gets a steady reading of 17 5 ohm.
How much current is flowing through the strobe light.
The current i in amps a is equal to the square root of the power p in watts w divided by the resistance r in ohms ω.
How much resistance is in a toaster that draws 5 amps of current when plugged into a 110 volt wall socket.
A 110 volt wall outlet supplies power to a strobe light with a resistance of 2200 ohms.
The filament of a light bulb is an extremely thin wire.
In simplified terms power voltage x current.
Fields should be reset to 0 before each new calculation.
The current i in amps a is equal to the power p in watts w divided by the voltage v in volts v.
9 v 5 a r.
A bulb draws 0 5 amps of current on a 9 volt battery.
The voltage is 120 volts and a 120 watt bulb has 1 amp flowing through it.
How much resistance should you put in the 110 volt circuit so that the light bulb only draws 0 5 amps of current.
110 v 0 5 a r.
Click calculate to find out the electricity cost of a single led light bulb running at 10 watts for 5 hours a day 0 10 per kwh you can also modify the input fields if needed.
When connected to a 120v power supply how much current exists in a light bulb that has a resistance of 240 ohms 1 2 amp how much power is used by a 6 0 v flashlight battery that draws a 0 5 a of current.
Voltage e current i resistance r.
So if a 120w light bulb is plugged into a 120v standard outlet it will draw 1 amp of current 120w 120v x 1a.
This thin wire resists the flow of electrons.

So i figured out the amperage for that with i p v 60w 120v 0 5 amps.
You can calculate the resistance of the wire with the resistance equation.
What is the resistance in the circuit.
Watts are units of power.
