Question

Two identical light bulbs are connected in series, as shown below. Which bulb will be brighter? A. A B. B C. Same brightness. A small current loop with magnetic moment mu is placed on the axis of a bar magnet, near the north pole and pointing in some arbitrary direction. The effect of the bar magnet's magnetic field on the current loop will be to... A. Cause mu to point towards the magnet. B. Cause mu to point away from the magnet. C. Cause mu to point perpendicular to the magnet. D. The magnet will not affect the current loop because the forces on the loop add to zero.

Explanation / Answer

1) two bulb are connected in series. so first bulb (bulb A) will get better brightness than the bulb B. because in series circuit voltage drop will be there, but current will be same. due to voltage drop in series circuit , we don't use series ciruit figure in our home, only use parallel circuit figure. in parallel circuit figure voltage will be same.

2) dont't have depth knowledge abot second question.
