The Control of Electricity in Circuits

The Control of Electricity in Circuits1a) Whats the difference between current electricity and static electricity? Current electricity is the flow of electrons in a circuit through a conductorStatic electricity is the electric charge that builds up on the surface of an object. Static electricity discharges when it is given a path, but it does not continue to flow Electricity vs. Static ElectricityAC vs DC1b) What do AC and DC stand for and whats the difference between them?Alternating current (AC) flows back and forth at regular intervals called cycles. Direct current (DC) only flows in one direction

Current Electricity2. a) Define Current electricity ?Current electricity is the continuous flow of electrons in a circuit2 conditions must be met for electrons to flow continuously:(1) The flow of electrons requires an energy source(2) The electrons will not flow unless they have a complete path to followWhat is an electrical circuitAn electric circuit includes an energy source, a conductor and a load

Electric Circuits

See figure 11.4 on p.434Electric Circuits4a) electrical loadconverts the electrical energy to another form of energy4b) switchA device that turns the circuit on/off by closing or opening the circuitWhen the switch is closedthe circuit is complete and electrons (-) can flowAn open switch means there is a break in the path so the electrons cannot flow through the circuitThe circuit is turned OFF when the switch is open.

Circuit Diagrams5a) What is a circuit diagram?Diagram with special symbols thatshow the components andconnections in a circuit5b) Why are they useful?Makes it easier to plan and analyze a circuit before you build it.5c) List the 2 rules to follow when drawing circuit diagrams:Always use a ruler to draw straight lines for the conducting wiresMakes right angle corners so that your finished diagram is a rectangle

Series and Parallel Circuits7a) What is a series circuit?A series circuit has components that are arranged one after another in series. 7b) How many paths does a series circuit have to allow the flow of electrons? one8a) What is a parallel circuit?A parallel circuit has parts that are arranged so that the electrons can flow along more than one path
