A choke coil takes a current of 2. 5 a when connected to 250 v, 50 hz supply and consumes 400 w. Find (i) the power factor (ii) resistance of the coil (iii) and inductance of the coil.

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
