demonstrates that the advantages and disadvantages of series and parallel circui
Term | Definition |
---|---|
electric current | the rate at which charges pass the through a given point; measured in amperes |
potential difference | the difference in potential energy between two loctaion |
voltage | the potential difference between two points; measured in volts |
insultator | the 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 that does work using electrical energy |
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 |
conductor | a material that allows heat or electrical energy to flow through it easily |
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 as that the potential difference across each part is the same |
