Question

Show how u qould connect 3 resistors each of resistence 5 ohm so that the combintion has a resistence of 3.33 ohm

Answer 1

Connect two 5ohm resistors in series

So the equivalent resistance will be 10 ohms. Then connect this in parallel with the remaining 5 ohm resistor

1/R=1/10+1/5=3/10

R=10/3=3.33
