Can a 230 volt bulb be used on a 120 volt circuit How does this impact wattage of the bulb?

Yes, a 230V bulb can be used on a 120V circuit, but the power output of the bulb will be approximately one quarter. (Half the voltage and half the current) Note, however, that since the bulb will be cooler, the resistance will be slightly less, so power will be somewhat higher than expected, but estimated figure is still one quarter.

What is the best wattage bulb to use in a bedroom lamp?
The wattage of bulb one uses in a bedroom lamp depends on several factors. If it is a lamp used for back ground lighting or a night lamp, one would use a very low wattage bulb. If it is for a bedroom reading lamp, one would want a stronger wattage. The biggest factor on deciding what wattage to use is the wattage suggested by the lamp manufacturer. All lamps are marked with recommend bulb wattage.
How do you prove that it is the wattage and not the physical size of a light bulb that matters for energy use?
Energy use is measured in watts. The watts used by a light bulb is on the package or the bulb. Find bulbs with the same wattage but different physical sizes if you want to prove this.
Can bulb wattage safely exceed that which is recommended on the fixture?
No, it is not safe to exceed the recommended wattage on a fixture. The wattage rating indicates the maximum amount of power that the fixture is designed to handle safely. Exceeding this wattage can cause overheating, fire hazards, and damage to the fixture. Always follow the manufacturer's recommendations for bulb wattage.
Can a dimmer be used with the 120 volt lighting fixture with a 230 volt bulb?
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.
Which wattage is used if you put a 3 way bulb into a lamp that does not have 3way ability?
The medium filament will be the light producer. This is because that filament is connected to the center pin of the lamp base the same as ordinary light bulbs. If the tri-light bulb is 50, 100 and 150 watts, the 100 watt portion will light.

What is the switch and the bulb in electricity?
A switch is used of stop the current flow in a circuit and the bulb can be classed as the load in a circuit.

Why does an electrical breaker trip when you use a lot of appliances in the house?
since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
What happens when a bulb gets fused?
When a bulb fuses the circuit is broken if it is on a serial circuit. If the bulb is on a parallel circuit, only the fused bulb will go out, any other bulb would remain lit. On a serial circuit, until the bulb is replaced by a new one, the circuit is not able to be used.
What is the Function of light bulb in an electric circuit?
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
Can bulb wattage safely exceed that which is recommended on the fixture?
No, it is not safe to exceed the recommended wattage on a fixture. The wattage rating indicates the maximum amount of power that the fixture is designed to handle safely. Exceeding this wattage can cause overheating, fire hazards, and damage to the fixture. Always follow the manufacturer's recommendations for bulb wattage.
What is the symbol used in a formula to represent the rate of energy dissipation in an electric circuit?
"W" for watts, or wattage
Will changing circuit breakers in box for electric heat reduce heating bills?
No, all it will do is make the circuit unsafe if a larger breaker is installed or make the circuit trip unnecessarily if a smaller breaker is installed. You pay for the wattage that you use. Less wattage used, less cost on your utility bill.
