S8P5.a
demonstrates the (dis)advantages of series & parallel
| Term | Definition |
|---|---|
| electric currents | rate at which charges pass through a given point- measured in amperes |
| potential difference | difference in potential energy between 2 locations |
| voltage | potential difference between 2 points - measured in volts |
| insulator | material that doesnt conduct heat of electrical energy well- often used to prevent energy from leaving a particular area |
| circuit | closed path through which electricity can flow |
| load | device in a circuit that does work using electrical energy |
| conductor | material that allows heat/electrical energy to flow through it easily |
| resistor | object added to a circuit that restricts the flow of electrical energy -inhibits the flow of electric current by producing a voltage drop when a current passes through it |
| switch | device used to control the flow of a current through a circuit |
| series circuit | circuit in which the parts are joined on after another such that the current in each part is the same |
| parallel circuit | a circuit in which parts are joined in branches such that the potential difference across each part is the same |
