Question

arrange 3 identical resistors in all the possible combinations and calculate the equivalent resistance. the resistance for each resistor is 200 ohms

Answer 1

Step-by-step explanation:

All R's in series: just add them together : 200 + 200 + 200 Ω = 600Ω

One in series with two in parallel :

= 200 Ω + 200*200/(200+200) Ω = 300Ω

All three in parallel :

R = 1 / (1/200 + 1/200 + 1/200) = 66.7 Ω
