There are eleven combinations of two, three or four of theresistors in your lab kit. Take each combination separately,connect the resistors in parallel and measure the equivalentresistance. Which combination will have the smallest equivalentresistance? Why? Show your calculations.I found R1 = 1.0K ohm ; R2=9.9k ohm; R3=2.2K ohm; R4= 0.10k ohm;battery voltage, V= 1.5V; current I coming from the battery =0.000114A;How do i calculate all eleven equvalent resistances R12, R13, R14,R23, R24, R34, R123, R124, R234 and R1234?
Light from a helium-neon laser (λ = 633 nm) is used to illuminate two narrow slits. The interference pattern is observed on a screen 2.7 m behind the slits. Eleven bright fringes are seen, spanning a distance of 55 mm.
What is the spacing (in mm) between the slits?
