Dear Sir,
What is the method of finding the resistance value in a given circuit when one value of one of the resistance.Given E (EMF),one resistance in circuit, value of second resistance to be worked out to get maximum power.
I tried to find as below
min resistance will give max current.
I^2R will be max
as resistances are in series, for min equivalent resistance, external resistance has to be minimum.
