Answer to Question #193532 in Electrical Engineering for shayla

Question

If you can not find a 325-ohm resistor in an electronics store, what can you do with a 300-ohm and 25-ohm resistor to get the resistance you need?

Answer 1

To get the resistance you need, you can simply connect the 300-Ohm and 25-Ohm resistors in series, and their equivalent resistance will be

$$R_e=300+25=3225\Omega.$$
