Three resistors are connected to a 12 V battery as shown in the figure given below:
The potential difference across the parallel combination of 6 ohm and 12 ohm resistor is:
Compare the power used in 2 ohm resistor in each of the following circuits
a)6 volt battery in series with 1 ohm and 2 ohm resistors
And
b)4 volt battery in parallel with 12 ohm and 2 ohm resistors
