S8P5.b
demonstrates the advantages and disadvantages of series and parallel circuits.
Term | Definition |
---|---|
electric current | the rate at which charges pass through given point; measured in amperes. |
potential difference | the difference in potential energy between 2 location. |
voltage | the potential difference between 2 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 energy. |
load | a device in a circuit that does not 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. |
