Temperature Variance of Resistance

Electrical resistance or simply resistance is the property of a material that opposes the free flow of electrons through it. The total amount of resistance to the flow of charges (or current) is affected by many factors like the length of the conducting material, its cross-sectional area, resistivity, and temperature.

Question

2. You need a 45 Q resistor, but the stockroom has only 20 Q and 50 Q resistors. How can the
desired resistance be achieved under these circumstances? What can you do if you need a 35 0
resistor?
