When connected to a 110-volt power supply how much current does a light bulb draw when it has a resistance of 220-ohms?
The formulas you are looking for is I = E/R.
A 9.0 volt battery connected to bulb. if a current of 0.25 Amps flows through bulb what is the resistance of bulb?
V = IR Voltage = Current * Resistance so 9 = 0.25 * R Hence R =36 Ohms
How do you know whether to get 120 volt or 130 volt light bulb?
If you want your bulbs to last longer then use 130 volt bulb on a 120 volt system. The light emitted by a 130 volt bulb, when comparing it to a 120 volt bulb, will be a bit dimmer.
Can you use a 13.5 volt light bulb in place of a 12 volt Will it be burn as bright?
A 13.5 volt bulb will burn less brightly but last longer.
What happen if a 110 volt lamp connected on a low voltage?
If you had a 60 watt incandescent bulb it would draw about 1/2 amp. That means that the resistance of the bulb filament would be about 220 ohms. Now if you applied 12 volts DC across 220 ohms you would draw about .05 amps. This would not be enough to heat the filament and create any useful light. Remember Ohm's Law says Volts = Amps x Ohms.
What is the resistance of a 28 watt bulb?
That depends on what voltage it's designed to operate from. Power = (voltage)2 / R R = Voltage2 / power If it's a 117-volt bulb, R = (117)2 / 28 = 489 ohms. If it's a 240-volt bulb, R = (240)2 / 28 = 2,057 ohms.
How many amps in a small table lamp?
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
How many ohms are there in 1volt?
There is 1 ohm in 1 volt.
How many 1.5 volt batteries does take to light up a big light bulb?
Is the bulb a 1.5 volt bulb? A 3 volt bulb? A 12 volt bulb or a 120 volt bulb?Or does it have some other voltage such as 230 volts which is very common in Europe and many other countries of the world?What is the wattage of the "big light bulb"?This question cannot be answered without knowing at least the voltage and the wattage of the light bulb that is being asked about.

What size resistor is needed to drop 12 volt dc to 3 volt what is the formula?
The "size" (value or the power capacity) of the resistor can not be defined unless the power of the 3 volt bulb is known. If you tell me how many amps would the bulb draw from a 3 volt source, I will tell you exactly how many ohms of resistance, and how many watts of power capacity will be required of the resistor.
What gives the biggest resistance 3 volt bulb or 6 volt bulb?
3 volt bulb gives the biggest resistance
Can you use a 120 volt bulb in a 130 volt socket?
Can you use a 120 volt bulb in a 130 volt socket?

How many amps if there is a 12 volt electrical system and 50 ohms resistance?
0.24 ampere
How much curretn is in a circuit that includes a 9- volt battery and bulb with a resistance of 12 ohms?
Current, I is equal to V (voltage) divided by R (resistance); Hence: I=V/R = 9V/200 ohms: I = 0.045 Amps, or 45ma (milliamps).
