To find the resistance in ohms of a 194 12-volt bulb, you can use Ohm's Law (R = V/I). The 194 bulb typically has a current rating of about 0.25 amps. Using this information, the resistance would be approximately 48 ohms (R = 12V / 0.25A).
The formulas you are looking for is I = E/R.
V = IR Voltage = Current * Resistance so 9 = 0.25 * R Hence R =36 Ohms
Choose a bulb with the same voltage as your fixture to prevent damage or risk of overheating. If the fixture specifies 120 volts, use a 120-volt bulb. If in doubt, consult the manufacturer's instructions or a professional electrician.
A 13.5 volt bulb will burn less brightly but last longer.
Yes, but a fact has to be taken into account that when a 230 volt rated bulb is used on a 120 volt system the wattage output is half of what the 230 volt bulb is rated at when it operates on 230 volt. So the dimmer will only be used to control half of the bulbs wattage which could bring the bulb down to a dull glow in full dimming position.
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.
There is 1 ohm in 1 volt.
The formulas you are looking for is I = E/R.
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.
3 volt bulb gives the biggest resistance
0.24 ampere
V = IR Voltage = Current * Resistance so 9 = 0.25 * R Hence R =36 Ohms
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.
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).
...90 volts...
It is not recommended to use a 120 volt bulb in a 130 volt socket as it can cause the bulb to burn out faster or even lead to safety hazards. It is important to match the voltage rating of the bulb with the socket for optimal performance and safety.
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.
