Why are metal strips thick in a metre bridge?

A strip of nickel metal is placed in a 1molar solution of Ni(NO_3)_2 and a strip of silver metal is placed in a one molar solution of AgNO_3 . An electrochemical cell is created when the two solution are connected by a salt bridge and the two strips are connected by wires to a voltmeter. (a) Write the balanced equation for the overall reaction occuring in the cell and calculate the cell potential. (b) Calculate the cell potential, E at 25^@C for the cell, if the initial concentration of Ni(NO_3)_2 is 0.100 molar and the initial concentration of AgNO_3 is 1.00 molar. [E_(Ni^(2+)//Ni)^@=-0.25V, E_(Ag^+//Ag)^@=0.80 VJ] log10^-1=-1
