Physics Concepts on Electricity and Circuits

These flashcards cover key concepts from the lecture notes regarding electricity, charge interaction, and circuit analysis.

What happens when a polythene rod is rubbed on hair and placed near a slow stream of water?

The positive side of the water's dipole bends towards the charged rod.

What is the net charge on hair after rubbing a polythene rod against it?

The net charge on the hair is negative after rubbing.

What combination correctly describes the charge acquisition of the polythene rod and hair?

The correct combination is B: i, ii and iii.

How do the readings on ammeters A1, A2, and A3 compare in a circuit with series components?

A1 = A2 + A3.

What does a dipole charge in water indicate in relation to a charged rod?

The positive side of the dipole charge in water is attracted to the charged rod.
