Question

Compare the power used in the 2 Ω resistor in each of the following circuits (i) a 6 V battery in series with 1 Ω and 2 Ω resistors, and (ii) a 4 V battery in parallel with 12 Ω and 2 Ω resistors.​

Answer 1

Explanation:

6 V battery in series with 1 Ohm and 2 Ohm resistors

1 Ohm and 2 Ohm resistors are connected in series. This current will flow through each component of the circuit because there is no division of current in series circuits. Hence, the current flowing through the 2Ohm resistor is 2 A.
