three 240 ohm resistors can be connected together in 4 different ways..?

making combinations of series and/or parallel circuits. What are these 4 ways, and what is the net resistance in each case?

240/3 = 80Ω (all 3 in parallel) 240×3 = 720Ω (all 3 in series)240/2+240 = 360Ω (2 in parallel with third in series)240×2 = 480480×240/(240+480) = 160Ω (2 in series all in parallel with third).... Show More

Right, you can have them connected in straight off series (3 in a row) giving R=240+240+240—-===—–===—-===–Or 3 in parallel in which case1/R = 1/240 + 1/240 + 1/240 —===—–===–/-===-/Or you could have two in parallel, which is then attached to another.Giving R=240+r where 1/r = 1/240+1/240–===—-===–-===-/Finally you could have a situation where there’s 2 in series, in parallel with anotherThis would give 1/R = 1/240 + 1/480—===–===—- —–===——-/Do the maths 🙂...

All 4 in series, 2 in series with 2 in parallel in series, 1 in series with 3 in parallel, all 4 in parallel. If you can think of any other possible configurations, you tell me! I say 4.... Show More

all parallel, all series, two in series parallel with another, two in parallel in series with another.equivalent resistance in parallel = 1/R1 + 1/Rn (add reciprocals)equivalent resistance in series = R1+Rn (just add’em up)... Show More
