why kitchen light becomes a bit dimmer when a toaster is turned on.?

Answer 1

The toaster and the room lights are on the same circuit. While not really bad, it should be of some concern. You might try finding a different circuit that is being supplied by a different breaker, or fuse, and move the toaster to that circuit. I am going to guess, since this is widely done, that the circuit that the kitchen is on, the lamp as well as the toaster, are in an over lap circuit from a different room. That can be found by turning off other loads in an adjacent room to see if the brightness of the lamp improves.
Plugging in a laptop will never improve available power. Buying a more "green" toaster is a waste of money. All toasters use resistance heating to toast the bread. The extra time needed for a lower wattage toaster would offset any savings, or reduction of power used.
If, and only IF the wiring can with stand the extra current available, have the breaker that serves the kitchen increased to no more than 20 amps. An electrician can determine that. If the kitchen already has 20 amp service, then you need to reduce the power demand on it that hasn't been mentioned.

The light is dimming because the voltage is dropping slightly. All electrical wires have some resistance to them. The longer the wire, or the smaller the gauge -- the more resistance. When current flows through the wires, a voltage drop occurrs. Voltage Drop = Amps x Resistance.

Increasing the amps (turning on the toaster) will increase the voltage drop.

Unlike a motor, there is no "surge" or "inrush" of a toaster. The toaster in my house draws approximately 12 amps. Turning on the toaster causes an extra 12 amps to flow through the wires, causing a small voltage drop that is most notable with incandescent lights. It is not uncommon for people to notice a voltage change of 2 volts. This could be a voltage change from 120 to 118 V.

This will be especially noticable if the kitchen light is on the same circuit as the toaster. The laws of physics are at work here -- there will always be a voltage drop. The magnitude of the drop is affected by the circuit configuration in your house, the external wiring from your house back to the utility transformer, and the electrical load.

It is possible that there is a loose connection or other wiring problem occurring. If the lights are dimming elsewhere in the house, then it is possible that the problem is outside your house -- on the utility's wiring between the transformer and the meter.

Answer 3

Although ideally, a voltage source (such as a wall plug) maintains a constant voltage, in reality, there is some resistance associated with it. Thus, when turning on a toaster, you are decreasing the resistance of the parallel circuit of the kitchen, causing a greater voltage drop accross the non-ideal resistance inherent in the power supply. After a short time, the system will stabilize itself, and ideal voltage will be restored, returning the lights to their normal brightness.

Re: above, the lights on a computer become brighter when you plug it in because when running on battery, a laptop enters "power saving" mode, dimming the screen. Check power options in the control panel to disable this feature.

Yer light is toasted? Good comedians those electrical guys huh?!
If you have a cowboy as best micky then you know makin' toast becomes a lil tricky!

That must been some powerful toaster ye got burning there? How many watts is it? It seems to be sucking all the available energy away from the rest of the bulbs glowing there.
If the imbalance become a strain then adding an extra toaster could mean that the fuse will get blown. Check the quality of the light bulb - watts and output - try to use the modern green lights - they use much less power and give twice the amount of light. Of course the toaster needs to be looked into also - try to get one at lesser watt requirement.

Answer 5

The power is dropping.

Every room in your home has a circuit for it which is usually limited to 20 amps. Any heater, like a toaster, uses a lot of electricity to generate the heat required. What is happening is the toaster is drawing more power (more wattage). Since the voltage is usually constant that means the amperage drops and power = voltage X amperage. So your power level is dropping, and your circuit is near to the maximum limit.

I wouldn't worry about it since the toaster is only on for a few minutes and if there is a problem then the circuit breaker will flip off if you are using too much power.

Answer 6

Because a toaster uses a lot of current and so detracts from the current available to power the lightbulb.

You can tell how much current used if you look at the power rating of an appliance, which is given in Watts. The equation is P = IV. If, for example, an appliance had a power rating of 2400W and mains voltage is 240V then that would be drawing 10A of current, which is quite a lot for a household appliance.

Answer 7

this is because of the fact your circuits are related in parallel yet,,, one abode can in straightforward terms use x volume of potential in line with time. So your kitchen easy turns into dimmer because of the fact the toaster want extra potential to technique it.

Answer 8

The circuit might be too heavily loaded. If you have another plug in your kitchen, your toaster might work better and your light may not dim.

Answer 9

because it is taking power from the kitchen light to run the toaster. If you have a lap top you will notice that when you plug it in the lights become brighter then when you were just running off of the battery

Answer 10

because its on the same circuit,and the toaster uses more electricity
