Question

3. How does electricity flow in an electric circuit ? What is meant by an open circuit?
​

Answer 1

Answer:

An open circuit implies that the two terminals are points that are externally disconnected, which is equivalent to a resistance R=∞ . This means that zero current can flow between the two terminals, regardless of any voltage difference.

Explanation:

Answer 2

Answer:

Electrons, which continuously move in wire, are called Electric Current. ... Current is the flow of electrons, but current and electron flow in the opposite direction. Current flows from positive to negative and electron flows from negative to positive.

Open circuit: If there is any gap in the path of a circuit, the bulb does not light up. Such a circuit is called an open circuit. Closed-circuit: The bulb lights up only when a bulb and wire form a complete path, which starts at one terminal of the electric cell and ends at the other terminal.
