Question

a 22 kilo ohm resistor having a tolerance of 10% has failed. you have on hand five resistors, valued at 120, 220, 47, 33 and 120 kilo ohm respectively. what combination of these would you choose to connect in parallel to replace the failed component?

Answer 1

Select:
R1 = 33k
R2 = 120k
R3 = 120k

1/Req = 1/33k + 1/120k + 1/120k = 0.0469697k
Req = 21.3k

Answer 2

How do i sketch the circuit diagram of the resultant?
