Question

Three resistor of 12 ohm 15 ohm 20 ohm connected in series & then in parallel . Calculate effective resistance in each case.

Answer 1

Hello ☺

$<b>$
Resistors : 12 ohm , 15 ohm , 20 ohm .


In series : R1 + R2 + R3 = 47 ohm


in parallel : 1/R1 +1/R2 + 1/R3 = 5 ohm

Answer 2

hey mate here is your answer ✌♥✌

❤ for series ♒

Re = R1 +R2+ R3

=12+15+20

=47OHM

❤IN PARALLEL ♒

RE = 1/R1 +1/R2 +1/R3

=1/12 +1/15 +1/20

=5ohm

hope it will be helpful to you ✔✔
