CIRCUITS AND ELECTRICAL SAFETY

THREE THINGS EVERY CIRCUIT MUST HAVE Energy Source Conductor Closed Circuit

VENN DIAGRAM OF SERIES AND PARALLEL CIRCUITS 1. bulbs light dimly 2. bulbs light brightly 5. there is only one path for electrons to travel 4. there are several paths for electrons to travel 6. when one bulb goes out, all bulbs go out 8. there is a lot of resistance in these wires 3. can have more than one bulb in a circuit 7. when one bulb goes out the others stay lit 9. there is little resistance in these wires

Definition: SHORT CIRCUIT is a connection that allows current to take the path of least resistance Are formed by: a conductor forming an unintended path

WHAT IS THE DIFFERENCE BETWEEN A STATIC SHOCK AND TOUCHING A FALLEN WIRE? The severity depends on the current. Never, ever touch a fallen wire, this will result in death if the wire is carrying current.

PLUGS 2 FLAT PRONGS Connects to the household circuit. One prong all the current to flow into the appliance, while the other prong allows the current to flow out of the appliance. ROUND PRONG Connects to a piece of metal in the “ground” wire. This is a safety feature. This is generally on appliances that use a lot of current.

FUSES AND CIRCUIT BREAKERS ARE IN HOMES TO PREVENT…. Circuits from over heating!
