Current and Circuits Power and control all rolled into one fun filled adventure…not really What Is A Current? • Current: the rate at which charges pass a given point Made by electrons moving in a wire AC/DC...what does that mean? • AC/DC: explains how current gets moved DC: Direct Current (one-direction) AC: Alternating Current (bi-directional) Voltage • Depends on Potential Energy • Voltage: the number of electrons that are in an energy source Voltage can vary Resistance • Resistance: opposition to the flow of charge Expressed in ohms Ώ As resistance increases…current decreases!!!! Ohm’s Law • Amperes (A) = volts (V) ohms (Ώ) I = Current V = Voltage R = Resistance I=V R Electric Power • The rate at which electrical energy is used to do work Expressed in Watts (W) P=VxI Power = voltage x current Circuits • Complete, closed path through which electric charges flow Closed Open Two Types of Circuits • 1. Series: all parts are connected in one loop Types Of Circuits • 2. Parallel: different loads are located on separate branches
