Two resistors, with resistances 5 Ωand
15 Ω are to be connected to a battery of emf
9 V so as to obtain:
(i) minimum current
(ii) maximum current
(a) Show with the help of a diagram how you would connect the
resistances in each case.
(b) Calculate the strength of the total current in the circuit
in each of the two cases.
