Question

when two resistors are connected in series their effective resistance is 80 ohm when they are connected in parallel the effective resistance is 20 ohm what are the values of the two resistance

Answer 1

The values of both the resistors are 40 Ohm  To verify it  Series-  R=r1 +r2  R = 40+40= 80 ohm Parallel - 1/R= 1/r1+1/r2 1/R=1/40+1/40=2/40=1/20 R=20ohm  Hence proved   Please mark the brainliest
