Basic Electrical Concepts
Electrical code calculations are based on fundamental electrical concepts. These include voltage, current, and resistance, which are interrelated by Ohm’s Law. Voltage (V) represents the electrical potential difference between two points in a circuit, current (I) is the flow of electrical charge, and resistance (R) opposes the flow of current.
Ohm’s Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor. Mathematically, it can be expressed as: V = IR.
Electrical Circuits
Electrical circuits are pathways that allow electrical current to flow. They consist of various components, including sources of electrical energy (such as batteries or generators), conductors (such as wires), and loads (such as lights or motors). Circuits can be designed in series, parallel, or a combination of both, each with its unique characteristics and applications.
