How does a wire helps in the flow of the current ?
Asked by vedangjaiswal2636.mpsl | 21st Apr, 2020, 08:40: PM
Electric currentis the rate of flow of charge. It is the amount of charge flowing through an area in unit time.
A continuous and closed path of an electric current is known as an electric circuit.
A wire is conductor made from metals like copper or aluminium which allow the flow of electrons from negative terminal to the positive terminal of the battery.
A battery provides the driving force required to move the charges along the wire from one terminal to another.
Copper and aluminium are commonly used metals to make wire because they provide low resistivity and current can easily flow through these metallic wires.

- Electric current is the flow of electrons. So, it should flow from the negative to the positive terminal. But my teachers say that the conventional direction of the current flow is high (positive terminal) to low (negative terminal) potential. Which statement is true? If both are true, then why? And please explain to me the difference between Direct and Alternating current. Please help, my exams are coming.

- In which direction current flows inside the cell?
- If we touch an electric wire carrying current, get a shock but when birds sit on it , they don't get any shock. Explain.
