Electricity is used for a wide variety of applications, from the computer you're using right now, to lighting, music, cars and industrial processes. For an electrical circuit to function it needs  a batterya closed loopa power sourcea closed loop and a power sourcean alternating currenta high resistance.
We discuss electricity in terms of current, which is  the energy carried around the circuitthe energy carried per chargehow much the circuit opposes the flow of chargethe magnetic field generated around the circuitthe rate of flow of chargethe power dissipated by the circuit, potential difference, which is  the power dissipated by the circuitthe rate of flow of chargehow much the circuit opposes the flow of chargethe magnetic field generated around the circuitthe energy carried around the circuitthe energy carried per charge, and resistance, which is  the power dissipated by the circuitthe magnetic field generated around the circuitthe rate of flow of chargehow much the circuit opposes the flow of chargethe energy carried per chargethe energy carried around the circuit.
Current has units of  ohms (Ω)volts (V)joules (J)amps (A)coulombs (C)watts (W). Potential difference has units of  volts (V)joules (J)amps (A)ohms (Ω)coulombs (C)watts (W). Resistance has units of  ohms (Ω)watts (W)coulombs (C)volts (V)amps (A)joules (J).
Components are placed in a circuit and may have different properties depending on current and potential difference.
 A thermistorAn ohmic conductorA diodeA filament bulbA voltmeterAn LDR has a constant resistance, no matter the current through it or the potential difference across it.
The resistance of  a filament bulba voltmetera diodean LDRa thermistoran ohmic conductor increases with the current through it, as the component heats up.
 A thermistorAn ohmic conductorA diodeA voltmeterAn LDRA filament bulb only allows current to flow through in one direction.
The resistance of  a voltmeteran ohmic conductoran LDRa diodea filament bulba thermistor changes with how much light it is exposed to.
