Question

Consider the following electric circuit : Calculate the values of the following :

Show how you would connect three resistors each of resistance 6 Ω, so that the combination has a resistance of 9 Ω. Also justify your answer.

State whether the currents and potential difference in all the bulbs will be same or different when in a circuit three bulbs of : (a) same wattage are connected in series. (b) same wattage are connected in parallel. (c) different wattage are connected in series. (d) different wattage are connected in parallel.

Two identical resistors of 24 Ω each are connected to a battery of 6 V. Calculate the ratio of the power consumed by the resulting combinations with (a) minimum resistance and (b) maximum resistance.
