Electricity+Definitions

Current: is the flow of charge. it flows from negative to positive. measured in amps (A). meausres how fast the charge flow, 1amps= 1 coulomb per seconds. measure current with an ammeter RESISTANCE Slows current ( flow of charges) Measured in ohms the length, thickness and the temputure of a wire effects the resistance. light bulb is a type of resister that changes electrial energy into heat energy and creating light .

conductor: allows charge to flow throught it. have a low resistance. E.g. metals insulator: Doesn't allow charge to flow through it. have a high resistance. E.g. plastic voltage: voltage occurs where energy is entering or leaving the circuit. measure in volts (V) with a voltmeter
