Answer is Wrong!
Answer is Right!
The correct answer is A. 1.4 V.
An Edison cell is a primary cell that uses a zinc anode and a manganese dioxide cathode. The electrolyte is a mixture of ammonium chloride and zinc chloride. The cell produces a voltage of about 1.4 volts when fully charged.
Option B is incorrect because the voltage of an Edison cell is about 1.4 volts, not 1 volt.
Option C is incorrect because the voltage of an Edison cell is about 1.4 volts, not 0.9 volts.
Option D is incorrect because the voltage of an Edison cell is about 1.4 volts, not 0.8 volts.
