Two resistors, with resistances 5ohm and 10ohm respectively are to be connected to a battery of emf 6 V so as to obtain:

minimum current flowing

maximum current flowing

How will you connect the resistances in each case?

Calculate the strength of the total current in the circuit in the two cases.

Given: Two resistors with resistances R1=5ohm and R2=10ohm, V=6volt

(a) For minimum current these two should be connected in series. For maximum current these two should be connected in parallel.

(b)In series,

Total resistance = 5+10 = 15ohms

Therefore total current drawn = V/R = 6/15 = 0.4amps

In parallel,

Total resistance R is given as

1/R=1/R1+1/R2

1/R=1/5+1/10

1/R=3/10

R=10/3ohm

Therefore total current drawn by the circuit = V/R = 6/(10/3) =1.8 amps
