Answer to Question #65737 in Electric Circuits for Helen

Question

We have a ton of 47 Ω resistors in the lab. I need a resistor that is closer to 70 Ω. Come
up with some way to wire multiple 47 Ω resistors (using series and parallel rules) to
produce an equivalent resistance of 70±3 Ω (your equivalent resistance can be anything
between 67 and 73 Ω). You can use as many resistors as you would like.
