Current

• Symbol I
• Flow of electrons around the circuit
• Measured in Amps (how fast the electrons travel around)

Voltage

• Symbol V
• Driving force that pushes electrons
• Measured in Volts (electrical pressure)

This video explains about Current and Voltages

Resistance

• Symbol R
• Slows down the electrons
• Measured in Ohms (resists the flow of the electrons)

The video below explains Resistance and Ohms Law

This video explains about resistance in different materials
