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 |
