Amperes: The unit of measurement for current
Charge: Whether there are more electrons or protons in a substance (negatively charged electrons vs positively charged protons) Positive and negative charges attract each other.
Coulombs: The rate of flow of current
Current: The rate of flow of electrical charge
Ohms: Unit of measurement of resistance
Potential difference: Also called voltage, it is the number of joules per coulomb, or the energy transferred per unit of current flowing per second.
Power: Rate of energy transferred.
Resistance: Anything that slows the flow in a circuit, increased by more components in series.
Voltage: Also called potential difference, it is the number of joules per coulomb, or the energy transferred per unit of current flowing per second.
Volts: Unit of measurement of voltage
Watts: Unit of measurement of power
