Calculate the Power Used in the 2 ω Resistor in Each of the Following Circuits: a 6 V Battery in Series with 1 ω and 2 ω Resistors. - Science

Calculate the power used in the 2 Ω resistor in each of the following circuits:

a 6 V battery in series with 1 Ω and 2 Ω resistors.

Solution

As the 6 V battery is connected in series, the potential difference will be different across the two given resistors. So we need the current to calculate the power.

Therefore, the net resistance, R of the circuit

= (1 + 2) Î = 3 Î

Current, I=V/R=6/3=2A
Power consumed by the 2-ohm resistor,
P = I2 R
= 2x 2
= 8 W

Is there an error in this question or solution?
