How would one go about calculating the resistance between points A and B on the following circuit:
This is for Higher Secondary level. The person who needs to solve this understands these basic rules:
-> Combined resistance of two resistors in series is the sum of their individual resistances.
-> Resistance of two resistors in parallel is the inverse of (1/R1 + 1/R2)
-> Ohm's law, V=IR
Furthermore, I know how to calculate the combined resistance if either one of R2 or R6 was absent (it would be 100 + (1/100+1/200)^-1), but their combined presence makes this confusing.
