What is the e.m.f of the Bichromate cell ?

A cell of e.m.f. 4 V and of negligible internal resistance is connected in series with a potentiometer wire of length 400 cm. The e.m.f. of a Leelanche cell is found to be balacned at 150 cm from the positive end of the potentiometer wire. What is the e.m.f. of the Leclanche cell ?

With a certain cell, the balance point is obtained at 65 cm from the zero end of a potentiometer wire. With another cell, whose e.m.f. is less than that of the first by 0.1 V, the balance point is obtained at 60 cm. What is the e.m.f. of the first cell ?

A cell of e.m.f. of 1.08 V is balanced by a 216 cm length of a potentiometer. What is the length of the wire that would balance a cell of e.m.f. 1.5 V ?

The standard reduction potential of Zn^(2+)|Zn and Cu^(2+)|Cu are -0.76V and +0.34 V respectively. What is the cell e.m.f (in V) of the following cell? ((RT)/(F)=0.059) Zn//Zn^(2+)" "(0.05M)//Cu^(2+)(0.005M)//Cu

The e.m.f. of a cell is a

A cell of e.m.f. 2 V and negligible internal resistance is connected in series with a potentiometer wire of length 100 cm. The e.m.f of the Leclanche cell is found to balance on 75 cm of the potentiometer wire. The e.m.f. of the cell is

How is DeltaG related to e.m.f. of the cell ?

Three dry cells are connected as shown in the figure. If e.m.f of each cell is 2 V, then the e.m.f. of the combination is "_____" V.
