The electric current cannot flow through the circuit when the switch is open as the air then acts as a insulator and prevents the flow. Actually the electrons stop moving towards the positive terminal of the cell as the protons can no longer attract the electrons.
Shruti Dadhwal 8 years, 9 months ago
An electric current flows due to movement of electrons or ions.when a circuit is closed and complete, the electrons moves from one point to another thus making the electrons moves and thus current flows whereas if the circuit is not closed, the electrons cannot flow in the circuit ans hence current cannot flow.

Alternating current (AC) is the most efficient way to deliver electrical power. However, most electronic devices need direct current (DC) to function. For this reason, AC to DC converters are either a part of devices themselves or as part of their power cords. If you've built a device you wish to power from an AC outlet, you must add an AC to DC converte

A thin metal can is cleaned, a cup of water is poured in it and heated strongly so that water starts boiling. Heating of can is stopped and an airtight cap is screwed tightly over the cap. After that cold water is poured over it. The can gets crushed from all sides.
This happens because after boiling of water steam is given out and it pushes most of the air out of the can. When cold water is poured over it, the steam gets condensed creating a partial vaccum inside the can. Now air pressure outside is much greater than that inside, and so it gets crushed.

Time is important to a student because there is only limited time and there are so many things to accomplish. Homework has to be done, students need to sleep, and extracurriculars also need to be attended and taken care of. Students need to learn how to manage their time effectively so that they can accomplish everything they need to when they need to. Time is priceless wealth in our life. One who don't care about time can never achieve his or her goals in his/her life.By knowing the importance of time we should be very careful in utilization of our time. One should not waste time to be success in life.
