as a physical quantity synonymous with the total electrification of a body, is not, like heat, a form of energy. An electrified system has a certain amount of energy, and this energy can be calculated by multiplying the quantity of electricity in each of its parts by another physical quantit...
Making small talk is a way to start a conversation with a stranger when meeting for the first time. It isn't easy to make small talk with people. You don't know. Sitting by yourself and saying nothing at a party is rude. Making small talk is necessary to build business relations. Mak...

When a phone is set next to a speaker, it does not react because the EM wave emissions are minimal, but when there is an incoming call or message the EM waves emitted are stronger and these are caught in the speaker’s coils, generating electricity that makes the speaker produce static ...
What's more, let's start with small things, such as saving electricity by pulling out the plug when it is out of use, saving water by turning off the tap in time and saving paper by reusing it. In addition, when we go shopping, ...
If you ask "what is Static Electricity?" or "what is Current Electricity", different people will give you different answers. This happens because people cannot agree upon the meanings of the words "static electricity" and "current electricity". This is a serious problem. In science, we want...
Static electricity is the imbalance of positive and negative charges. Opposites Attract Now, positive and negative charges behave in interesting ways. Did you ever hear the saying that opposites attract? Well, it's true. Two things with opposite, or different charges (a positive and a negative...
Applications of static electricity While static electricity can be a nuisance or even a danger, as in the case of static cling or static shock, in other cases it can be quite useful. For instance, static charges can be induced by electrical current. One example of this is acapacitor, so...
