Power
A contractor wishes to lift a load of bricks from the sidewalk to the top of a building by means of a winch. Since we know the expression for work, we can calculate work to be done by the force applied by the winch to lift the load. We are interested in the rate at which it is done, that is, will t..

Electric Power
Electric Power - Power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flows through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the electric ..

Hydel Power
Electricity is obtained from flowing water. Water from the dam is allowed to flow through the tunnels at a high pressure. Turbines convert the potential energy of the water into electrical energy. About 23,800 MW of energy is generated by hydel power in India. Hydel power requir..
Power Factor
P = E r m s I r m s cos q . The product E r m s I r m s is called apparent power, whereas the P is called the true power. The term cos f is called the power factor. The current through pure L or pure C, which consumes no power for its maintenance in the circu..
Power of a Lens
Power of a Lens - Whenever a ray of light passes through a lens (except when it passes through the optical center) it bends. The bending of light rays towards the principal axis is called convergence and bending of light rays away from the principal axis is called divergence. The degree o..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
