5 Questions
What is electric current and what is required to maintain it?
Electric current is the flow of electric charge moving in a particular direction. To maintain an electric current, the charge needs a continuous path to travel around, known as a closed circuit.
Explain the difference between conventional current and electron flow.
Conventional current is the belief that electricity is the flow of positive charge around the circuit, represented as flowing from a positively charged point to a negatively charged point. Electron flow, on the other hand, is the actual flow of negative charge in the direction of the movement of electrons through the conductor.
How do electrons flow through a circuit and in what direction do they travel?
When electric currents pass through a circuit, the electrons in the conductor move to produce a flow of negative charge in the direction they travel. The negative charge flows from the negative points to positive points.
What was the early belief about the direction of electric current flow and how was it represented?
Early experiments believed that electricity is the flow of positive charge around the circuit, and therefore represented the flow of electric current as from a positively charged point to a negatively charged point using arrows to indicate the direction.
What is required for charges to produce an electric current and what is the actual nature of electric current flow?
Charges can produce an electric current if the charge can flow through a conductor. The actual nature of electric current flow involves the movement of electric charge, specifically the flow of negative charge in the direction of the movement of electrons through the conductor.
