demonstrates the advantages 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 electrical 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 of electrical energy to 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 |
