Here's a precise problem for the student to solve:A galvanic cell is constructed with a zinc electrode and a copper electrode in two separate solutions, connected by a salt bridge. The zinc electrode has a surface area of 4 cm² and the copper electrode has a surface area of 8 cm². The concentration of zinc ion solution is 0.1 M and the copper ion solution is 0.01 M. The temperature of the solutions is 25°C. Calculate the resistance of the electrochemical cell.
