What is charge explain?
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). An object with an absence of net charge is referred to as neutral.
What is the SI unit of charge?
Coulomb, unit of electric charge in the metre-kilogram-second-ampere system, the basis of the SI system of physical units.
What is charge example?
Many fundamental, or subatomic, particles of matter have the property of electric charge. For example, electrons have negative charge and protons have positive charge, but neutrons have zero charge. A negatively charged object has an excess of electrons on its surface.
What is charge very short answer?
Electric charge is a basic property of electrons, protons and other subatomic particles. This makes electrons and protons stick together to form atoms. Things that have the same charge push each other away (they repel each other). This is called the Law of Charges. It was discovered by Charles-Augustin de Coulomb.
What is the unit of power?
Watt
Power/SI units
Electricity is measured in units of power called Watts, named to honor James Watt, the inventor of the steam engine. A Watt is the unit of electrical power equal to one ampere under the pressure of one volt. One Watt is a small amount of power.

Is the charge of an electric current energy?
The words “electric current” mean the same as “charge flow.” Charge is not energy. A fixed quantity of charge can possess many different amounts of energy at the same time (and note the same charge in different values of capacitor.) Also, if you know the amount of charge present, you have no knowledge of the amount of energy.
Which is the correct definition of electric charge?
The definition of electric charge is given as follows: “Electric Charge is the property of subatomic particles that causes it to experience a force when placed in an electromagnetic field.” Is Electric Charge a Vector Quantity? Electric charge is a scalar quantity.
