What is a control switch?

a control switch is a sort of remote controlled relay attached to home appliances which consumes more power.


What happens to the overall resistance of a circuit when too many appliances are connected across a 120 V outlet?

This is a very technical electrical question that may be difficult to understand without further study. But adding appliances to an outlet is the same as adding resistance in parallel. Adding resistance in parallel, the resistance of the circuit goes down. That is why you get more current flow. By contrast, adding resistance in series increases the resistance of the circuit and therefore reduces current, all else being equal.


What will increase the voltage in a circuit?

There is a way to use capacitors to increase the voltage in an ac circuit. It increases it by about 50 %. It was used to increase the voltage going to motors. It is seldom used now that it is much easier to run a higher voltage line into a place of business. It does not work for Direct Current.


What is the effect on led by increasing or decreasing current?

An LED will shine brighter as more current is pushed through it. There is a dimishing return on this - at some point, increasing current will not increase the brightness very much, and will cost significantly more in terms of power.


Why does the current immediately increase in current after reaching a certain voltage rather than a gradual current increase?

It depends on the nature of the circuit. In a purely-resistive circuit, the current would rise immediately because resistance merely limits its value, it doesn't oppose any change in current. But in a resistive-inductive circuit, for example, the inductive component opposes any change in current, so the current will rise more gradually.

Why does adding more appliances to a circuit increase the current?

More appliances means more load are being added, which necessariliy increases the current.


Can a ground leakage damage electrical appliances?

A ground leakage can damage electrical appliances. When there is a current leakage, it causes the appliance to draw more current through thecircuit, hence produces excess heat. This can damage the appliances.


Does increase in crossectional area of a conductor increase or reduce current carying capacity?

Conductors with more cross-section area can carry more current than thinner ones. That's why you use a thicker "heavy duty" extension cord to run big appliances, and why the service drop from the pole to your house has wires as thick as your thumb.


Can you use number of appliances on a single transformer?

You can use multiple appliances as long as long as you don't draw more current than the transformer can supply.


Will any of the home appliances contribute to ozone depletion?

No more than anything that requires combustion of fossil fuels to power does. Ozone depleting chemcials that have been identified have been banned from current production. So older appliances might still be causing other damage...


If more and more appliances will be connected in a parallel circuit what do you think will happen?

Appliances have to be connected in a parallel circuit to keep the voltages the same for each appliance (they were designed to work with one voltage) , this does not mean that the power output will be the same, the more appliances there are the more current (i.e. power) will be needed to for the appliances and this can go on until the grid cannot supply any more (and you blow a fuse)


What makes commercial kitchen appliances?

Commercial appliances are usually much larger than regular appliances, more powerful, and don't have the same safety mechanisms that home appliances do because they are made for businesses. On the plus size, they are higher quality and make things around the kitchen more efficient.


The Best Home Appliances for Kitchen Efficiency?

Shopping for kitchen appliances requires much more work than shopping for any other types of home appliances. This is because appliances for the kitchen don't simply have to look good, but they have to have a functional purpose as well. Due to this, it's important to look for home appliances for the kitchen that aren't just very useful, but that can be found in attractive styles. The best home appliances in this category are a decent mixer, an attractive oven hood, and a solid metal coffee maker. This covers the most important appliances in your kitchen, and all of these can be found in attractive models.


How does the number of cells affect the current in a circuit?

More cells = more available power. Power = voltage * current. The orientation of the cells determines whether this power is delivered as more voltage, or more current. If the cells are in series, the voltage will increase proportionately and the available current will remain unchanged; if the cells are in parallel, the current will increase proportionately and the voltage will remain unchanged.


What can you increase by using more cells?

You can increase the current. It depends on how you add them, though: that is, how they are connected to each other.
