Newton has three law :- 1.Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion. 2.Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. 3. Every action has an equal and opposite reaction That's all these 3 newton's law select from these which law do u need...

Inductor coil is best option to connect in serie? Why?

Posted by Omi Neemwal 7 years, 11 months ago

CBSE > Class 12 > Physics

1 answers

Shobhit Rawat 7 years, 11 months ago

Inductors are said to be connected in “Series” when they are daisy chained together in a straight line, end to end. Inductors in series are simply “added together” because the number of coil turns is effectively increased, with the total circuit inductance LT being equal to the sum of all the individual inductances added together.
