Matchless Power Formula Class 10

Where V is the potential difference I is the electric current R is the resistance and P is the electric power Stay tuned with BYJUS for more such interesting articles.

Power formula class 10. This sheet of pdf consist of short notes formula important bullet points of science class 10th prepared by expert faculty members of entrancei for quick recap of the entire chapter-Electricity of class 10 science. Rate at which electric energy is dissipated or consumed in a circuit is called Electric Power. Power Work done by the object or body Total time taken.

1 Watt power is consumed when 1 Ampere of current flows through a device at a potential difference of 1 Volt. Less the current less heat produced. Which is related to how fast a job is done.

F mg 1000 x 981 9810 N. NCERT Solutions for Class 10 Social Science. This is known as Joules law of heating.

P VI I2R V2R SI unit of Power is Watt W. Power of a Lens Formula. Also find the magnification produced by the lens.

This is also known as diopter. The law implies that the heat produced in a resistor is directly proportional to the square of current for a given resistance It means if we double the currentthe heat becomes 4 times if we half the currentthe heat becomes 14 times Hencemore the currentmore the heat. Power formula can be rewritten using Ohms law as P I2R or P V2R.

The focal length f of a converging lens is considered positive and that of a diverging lens is considered negative. View Answer Example 104 - A 20 cm tall object is placed perpendicular to the principal axis of a convex lens of focal length 10. Power formula differs as per the required statements for example it can be different for force related objects and also can differ for electronic devices.
