(a) State Ohm's Law.
(b) Draw a schematic diagram of the circuit for studying Ohm's Law.

If a 12 V battery is connected to the arrangement of resistances given below, calculate
(i) the total effective resistance of the arrangement and
(ii) the total current flowing in the circuit

Three incandescent bulbs of 100 W each are connected in series in an electric circuit. In another circuit, another set of three bulbs of the same voltage are connected in parallel to the same source.
(a) Will the bulb in the two circuits glow with the same brightness? Justify your answer.
(b) Now let one bulb in both the circuits get fused. Will the rest of the bulbs continue to glow in each circuit? Give reason

State Ohm's law? How can it be verified experimentally? Does it hold good under all conditions? Comment

How will you infer with the help of an experiment that the same current flows through every part of the circuit containing three resistances in series connected to a battery?

How will you conclude that the same potential difference exist across three resistors connected in a parallel arrangement to a battery?
