Basic Electrical Engineering BEE-For Clearing Basic Concepts

Explore current as the flow of electrons through a conductor, measured with an ammeter, and apply I = Q/t to relate charge and time.

Learn how electrons flow from negative to positive charges to create current in conductors, and how this electron flow relates to conventional current.

Explore the current-voltage relation in a simple battery circuit, showing how current flows from negative to positive, devices rely on rated voltage, and higher voltage drives higher current.

Explore Ohm's law, showing how current relates to voltage through resistance, the conductor's opposition to current. Learn how material, cross-sectional area, and temperature influence resistance and its unit, the ohm.

Explore how increasing resistance causes greater voltage drop as the force moves electrons, explaining energy loss and how Ohm's law computes voltage drop across a circuit.

Explore magnetic flux, its dependence on magnetic field, surface area, and angle, and learn to compute the perpendicular component using the flux formula.

Explore electromagnetism by linking current through a conductor to the surrounding magnetic field, using the right-hand rule and convention current to determine field direction and magnetic flux.

Learn how a coil converts current into a magnetic field, use finger direction to determine field orientation, and note that magnetic strength rises with current and core material.

Identify how inductance depends on the number of turns, core material permeability, spacing between turns, coil shape, and coil diameter and size.

Capacitance stores energy in the electrostatic field between plates and opposes voltage changes; charging with a battery drives a high initial current that decays to zero, Q = C V.

Capacitance increases with larger plate area and decreases with smaller area. It also grows as the distance between plates shrinks and as the dielectric constant rises.

Explore series and parallel connections of resistance, inductance, and capacitance, applying Ohm's law to compute total and equivalent values in circuits.
