b-Two aluminum and copper wire resistors consume 0.5 W when connected in parallel to 2 V DC supply. The aluminum wire is 40% length more than copper wire. Calculate the power consumed by the two resistors when connected in series to the same DC supply. Assume equal cross-section area and the resistivity of aluminum is to be 20% more than that of copper.
