S8P5.b
Demonstrates the advantages & disadvantages of series & paralell circuts
Term | Definition |
---|---|
electric current | the rate at which charges pass thru a given point; measured in amperes |
potential difference | the difference in potential energy btw 2 locations |
voltage | potential difference btw 2 points; measured in volts |
insulator | material that doesn't conduct heat of electrical energy well; often used to prevent energy from leaving a particular area |
circut | a closed path in which energy can flow |
load | a device in a circuit that does work while consuming electrical energy |
conductor | a material that allows heat or electrical energy to flow through it easily |
resistor | an object added to a circuit that restricts the flow of electrical energy; inhibits the flow of electrical current by producing a voltage when a current passes thru it |
switch | a device used to control the flow of current thru a circut |
series circut | a circuit in which the parts are joined one after another such that the current in each part is the same |
parallel circuit | a circuit in which the parts are joined in branches such that the potential difference across each part is the same |
