Q.20. Two conductors A and B of resistance 5 ohmand 10 ohm respectivel

1.	Q.20. Two conductors A and B of resistance 5 ohmand 10 ohm respectively are first joined inparallel and then in series. In each case thevoltage applied is 20 V(a) Draw the circuit diagram to show thecombination of these conductors ineach case(b) In which combination will the voltageacross the conductors A and B be thesame?(c) In which arrangement will the current through A and B is the same?(d) Calculate the equivalent resistance for each arrangement
Answer» in series current will be same and in parallel connection voltage will be same The voltage across A and B is same when they are connected in parallel and the current is same when they are connected in series....for series arrangement the net resistance is 10+5=15 ohm and for the parallel one it is (10×5)/(10+5)=50/15=3.33 ohm thanks

Answer»

in series current will be same and in parallel connection voltage will be same

The voltage across A and B is same when they are connected in parallel and the current is same when they are connected in series....for series arrangement the net resistance is 10+5=15 ohm and for the parallel one it is (10×5)/(10+5)=50/15=3.33 ohm

thanks
