Electric Basics

Electric Basics

• Electric refers to the presence of electric charge, which can be either positive or negative.
• Electric charge is a fundamental property of matter, and it is responsible for the electromagnetic force, one of the four fundamental forces of nature.

Electric Charge

• There are two types of electric charge:
  • Positive charge (protons)
  • Negative charge (electrons)
• Like charges repel each other, while opposite charges attract each other.

Electric Current

• Electric current is the flow of electric charge, typically measured in amperes (A).
• It is the movement of electrons from one place to another, often through a conductor such as a wire.
• Electric current is characterized by its voltage (V), current (I), and resistance (R), which are related by Ohm's Law: V = I x R.

Electric Circuits

• An electric circuit is a path through which electric current flows.
• It consists of a power source, conductors, and loads (e.g., light bulbs).
• Electric circuits can be series, parallel, or a combination of both.

Electric Safety

• Electric shock can be fatal, so it is essential to handle electric devices and wiring with caution.
• Prevent electrical hazards by:
  • Avoiding overloaded circuits
  • Keeping electrical appliances away from water
  • Using protective gear (e.g., insulation, grounding)
