Problem 57PE

PE An old light bulb draws only 50.0 W, rather than its original 60.0 W, due to evaporative thinning of its filament. By what factor is its diameter reduced, assuming uniform thinning along its length? Neglect any effects caused by temperature differences.

Step-by-Step Solution:

Step-by-step solution Given : Change in Power of the bulb : P = 50.0 W, from P = 60.0 W 2 1 Calculate the diameter of the wire = Step 1 of 2 Now, We know that , Power is the rate of flow of energy. The power can be calculated from the formula, 2 P= V /R Here, R is the resistance through which current isflowing and V is the supplied voltage.
