1 Current and Circuits Power and control all rolled into one fun filled adventure…not really

2 What Is A Current? Current: the rate at which charges pass a given pointCurrent: the rate at which charges pass a given point Made by electrons moving in a wire

3 AC/DC...what does that mean? AC/DC: explains how current gets movedAC/DC: explains how current gets moved DC: Direct Current (one-direction) AC: Alternating Current (bi-directional)

4 Voltage Voltage: the number of electrons that are in an energy sourceVoltage: the number of electrons that are in an energy source Voltage can vary Depends on Potential EnergyDepends on Potential Energy

5 Resistance Resistance: opposition to the flow of chargeResistance: opposition to the flow of charge Expressed in ohms Ώ As resistance increases…current decreases!!!!

6 Ohm’s Law Amperes (A) = volts (V)Amperes (A) = volts (V) ohms (Ώ) ohms (Ώ) I = Current V = Voltage R = Resistance I = V R

7 Electric Power The rate at which electrical energy is used to do work Expressed in Watts (W) Power = voltage x current P = V x I

8 Circuits Complete, closed path through which electric charges flowComplete, closed path through which electric charges flow Closed Open

9 Two Types of Circuits 1. Series: all parts are connected in one loop1. Series: all parts are connected in one loop

10 Types Of Circuits 2. Parallel: different loads are located on separate branches2. Parallel: different loads are located on separate branches
