Because the entire universe is made up (Mostly) of positively and negatively charged sub-atomic particles.
The resistance in a material is the opposing force that charges flowing in electronic currents must overcome. Resistance is caused by collisions between moving electrons and the atoms of the material, which results in the conversion of electrical energy into heat. This opposition can slow down the flow of charges and reduce the efficiency of the electronic circuit.
Correct Answer= "To reduce or eliminate static charges"
The basic idea is to carry off excess electric charges, before they become dangerous - to humans, or to electronic equipment, depending on the case.
I think Scientist coulomb invented the electronics charges so on their name the unit of charge taken. they also gives the formula for consider force between two charges separate with distance r. also they gave the method to consider charges on any atom.
Felix Ehrenhaft has written: 'The microcoulomb experiment; charges smaller than the electronic charge'
Electrons... Electrons are the atomic particles that have a negative electronic charge
The charges for RTGS (Real Time Gross Settlement) and NEFT (National Electronic Funds Transfer) vary from bank to bank. Typically, RTGS charges are higher than NEFT charges because RTGS is used for high-value, time-sensitive transactions. It is recommended to check with your specific bank for the most accurate and up-to-date information on these charges.

There is no cost for using hsbc online if you are a HSBC customer. There may, however, be electronic transaction charges as well as charges applied by your internet service provider.
Electronic flow is true. Conventional flow was thought to have positive charges flowing from the + terminal to the - terminal. This was before we knew that it is actually the electrons which flow, and the positive charges cannot move out of their atomic nuclei. Now that electrons have been detected, and protons are known to stay within the nucleus unless a nuclear reaction takes place, we know that it is the electrons that flow from the - terminal to the + terminal. This is known as electronic flow.
An integrated circuit contains transistors, which can act as electronic switches that open or close the circuit for electrical charges. These transistors control the flow of current by switching between conducting and non-conducting states, enabling complex functions in electronic devices. They are fundamental components in digital logic circuits, amplifiers, and various applications in computers and communication devices.
As electric charges pass through batteries, they gain energy from the chemical reactions happening inside the battery. This stored energy can then be used to power devices connected to the battery, such as electronic gadgets or vehicles.
