Question

You are working late in your electronics shop and find that you need various resistors for a project. But alas, all you have is a big box of 10 ? resistors. Show how you can make each of the following equivalent resistors by a combination of your 10 ?
resistors: (a) 35 ? (b) 1 ? (c) 3.3 ? (d) 7.5 ?.

Answer 1

Do you have unlimited resistors?

Answer 2

no, only 10 ohms

Answer 3

yea but HOW MANY 10 ohms?

Answer 4

uhm sorry,you're right it has unlimited resistor.

Answer 5

Then all you gotta do is imagine
m resistors in series, and n such combinations in parallel.
What would be the effective resistance of such combo?

Answer 6

got it!

Answer 7
