See lessWhat is reverse osmosis?
Reverse osmosis is a process of movement of solvent through a semi permeable membrane from high concentration to low concentration when certain pressure is applied in it. It is quite opposite to the osmosis, which is a natural phenomenon. It is mostly used in the purification of water.

MCB stands for Miniature Circuit Breaker. It is an automatically operated switch to control the flow of current passing through it. It is used to cut the flow of current during open and short circuits.
Miniature circuit breakers are intended to prevent damage to an electrical circuit as a result of excess current. They are designed to trip during an overload or short circuit to protect against electrical faults and equipment failure.
MCB’s are more sensitive to current than fuses. They immediately detect any abnormality and switch off the electrical circuit automatically.
See lessWhat is pn junction diode?
A p-n junction diode is a semiconductor device which allows the current to flow through it in only one direction when connected in a closed circuit. It has a positive side(p) and negative side(n) which are created by adding impurities on both sides of the semi-conductor called doping. It can be connRead more
A p-n junction diode is a semiconductor device which allows the current to flow through it in only one direction when connected in a closed circuit.
It has a positive side(p) and negative side(n) which are created by adding impurities on both sides of the semi-conductor called doping.
It can be connected in a circuit in two ways named, forward bias and reverse bias. In reverse bias, the current flows in the opposite direction to that of the current in forward bias.

See lessAn electric heater draws 10A from a 120V line.The resistance of the heater is:
Resistance of electric heater= voltage/current Resistance = 120/10 = 12 ohm
Resistance of electric heater= voltage/current
Resistance = 120/10 = 12 ohm

I think all of us have known about the importance of time. It’s the most precious thing that cannot be brought back. The way we use it decides our future.We have to utilise it in a proper way. Wasting the time for unnecessary things is going to cost you a lot in your coming days.
Utilisation of time for good things is going to bring experience in life. And that experience is going to pay you for your future. Time heals everything and brings a lot of lessons.
Time cannot be brought back. Well,it can be controlled by time machines. But, scientists are not sure about that ?
