Current - rate of flow of charge carried by electrons around a circuit. Electrons are negatively charged, so get attracted to a positive battery. Symbol I, measured in Amps!
Voltage - Causes electrons to flow around the circuit. Bigger the voltage, the faster the electrons flow (bigger current). Positive energy that makes electrons move. Symbol: V Measured in: volts
Electricity - Movement of electrons around a circuit.
Charge - (+ or -) Electrons have negative charge -. Charge carried by electrons.
Electrons move randomly when there is no current.
Electrons go from - to +. Conventional current goes from + to -.
Electrons attracted to nucleus because nucleus is + charge and electrons are - charge.
Provide a cell to create positive and negative charge throughout a circuit.
Increase the VOLTAGE -- MORE CURRENT will flow.
Increase RESISTANCE -- LESS CURRENT will flow.
