I just want to convert the voltage into current i.e. suppose I have 750V & 1A AC power then I want to convert it into 12V & 62A DC power only difficulty is that I don't want to use the tranceformer. Simply to say, I want to make the step-down without using tranceformer. Please, give me some ideas. And also I want the relation between Magnetic Induction & Weight of the body can be levitated. Or I can say, how much of magnetic induction requires to lift 500gms weight? I am heartily thankful to you.
2215When a bicycle is in motion, the force of friction exerted by the ground on the two wheels is such that it acts a) In the backward direction on the front wheel and in the forward direction on the rear wheel. (b) In the forward direction on the front wheel and in the backward direction on the rear wheel. (c) In the backward direction on both the front and rear wheels. (d) In the backward direction on both the front and rear wheels.
