Question
(Ranking reminder, if the results were A=B> GD>E=F=G=H then the ranking will be A=1, B=1, G=2 D=3, E=4, F=4, G=4, H=4) Shown below is a DC circuit that contains a number of switches. Each switch is resistanceless when closed. All of the connecting wires may be considered to have zero resistance. All of the resistors shown are identical. The circuit contains an ideal ammeter. The diagram shows all of the switches open. Below the diagram are eight different switch configurations for the circuit. Rank these configurations in terms of the ammeter reading. That is. put first the configuration for which the ammeter gives the largest reading. and put last the configuration for which the ammeter gives the smallest reading. If two or more configurations produce the same ammeter reading. give these configurations equal ranking.Explanation / Answer
when all the switches are open
current is zero, reading iszero
when e close switch , then that resistence comes into existence
also I=V/R
in series
Rs=R1+R2
Rp=(R1+R2)/R1R2
B
net resistence=(2R+R)/2R2
C
net resistence=2R
I=V/R
as the resistence decreases current increases, if resitence is equal current is equal for that cases
