S8P5.b
demonstrates the advantage and disadvantages of series and parallel circuits
| Term | Definition |
|---|---|
| electric current | the rate at which charges pass through a given point;measured in amperes |
| potential difference | the difference in potential energy between two location |
| voltage | the potential difference between two points;measured in volts |
| insulator | a material that does not conduct heat of electric energy well;often used to prevent energy from leaving a particular area |
| circuit | a closed path through which electricity can flow |
| load | a device in a circuit that does work using 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 electric current by producing a voltage drop when current passes through it |
| switch | a device used to control the flow of current through a circuit |
| series circuit | 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 |
