Electric Current & Circuits Explained, Ohm's Law, Charge, Power, Physics Problems, Basic Electricity

This physics video tutorial explains the concept of basic electricity and electric current. It explains how DC circuits work and how to calculate voltage, current, and electrical resistance using Ohm's law. In addition, it shows you how to calculate the electric charge and the number of electrons flowing through a wire at any given point. In addition, it has a few examples and practice problems on electric power, cost of electricity in Kwh and other stuff as well. It provides visual drawings, equations, and formulas as well as the units of common variables that you'll encounter when dealing with electricity. It discusses the difference between conventional current and electron flow. The unit of electric current is the ampere or amps for short. The unit for resistance is ohms and for voltage is volts. 1A is 1C/s or 1 coulomb per second. Electric current is the rate of electric charge flow. Charge represents the quantity of electrons in the case of metal conductors. The unit of power is the watt which is 1 Joule per second. Power is the rate at which energy is transferred. Equations used include V=IR, P=VI, and Q=It.
