Question

compare the power used in 2 ohm resistor in each of the following circuit. 1) A 6 volt battery in series 1 ohm and 2 ohm resistor. 2) A 4 volt battery is parallel with 12 ohm and 2 ohm resistor. ​

Answer 1

To find : Compare the power used in 2 ohm resistor in each of the following Circuits, (1) a 6 V battery in series with 1 ohm and 2 ohm resistors. 1 Ω and 2 Ω resistors are connected in series. So, Equivalent resistance of the circuit is R=1+2=3 Ω.

Answer 2

Answer:

The voltage across each component of a parallel circuit remains the same. Hence, the voltage across 2 Ohm resistor will be 4 V. Therefore, the power used by 2 Ohm resistor is 8 W
