Understanding Conventional Current and Electron Flow

The video explains the difference between conventional current and electron flow. Conventional current flows from high to low electric potential, representing positive charge movement. In contrast, electrons, which are the actual charge carriers in metal wires, move from low to high potential. The video also discusses how electric fields affect protons and electrons differently, emphasizing the opposite directions of conventional current and electron flow. It concludes with a suggestion to explore more resources on electric circuits and electronics.

What is the direction of conventional current in a resistor with a potential difference from 20 volts to 15 volts?

• No flow

• Both directions

• From 20 volts to 15 volts

• From 15 volts to 20 volts

What is the potential difference across a resistor if one side is at 20 volts and the other at 15 volts?

• 5 volts

• 20 volts

• 35 volts

• 15 volts

In metal wires, which particles are responsible for the actual movement of charge?

• Electrons

• Neutrons

• Protons

• Ions

How do electrons move in a circuit with a battery?

• They do not move

• In a circular path

• From negative to positive

• From positive to negative

What happens to a proton placed in an electric field between two parallel plates?

• It moves towards the positive plate

• It moves towards the negative plate

• It remains stationary

• It moves in a circular path

How do negative charges behave in an electric field?

• They move towards the positive plate

• They move towards the negative plate

• They remain stationary

• They move in a circular path

What is the main difference between conventional current and electron flow?

• Conventional current is faster

• They move in the same direction

• They move in opposite directions

• Electron flow is slower

Which type of charge is associated with conventional current?

• Positive charge

• Negative charge

• Both positive and negative charges

• Neutral charge

In a metal, which particles are free to move and act as charge carriers?

• Electrons

• Neutrons

• Ions

• Protons

What is the role of electrons in a circuit?

• They do not participate in current flow

• They move towards the positive terminal only

• They are the charge carriers

• They remain stationary
