Question

b) Name the factors which can affect the internal resistance of the cell.
c) A cell of e.m.f.1.5V, internal resistance 1 ohm is connected the resistor of 4 ohm and 20
ohm in series. Draw a circuit diagram and calculate (i) current in circuit (ii) P.D. across each
resistor (iii) P.D. across cell​

Answer 1

Answer:

anwers are getting following:::----

Step-by-step explanation:

b) the internal resistance of a cell depends on the factors like distance between the electrodes, the temperature, the effective area of the electrodes and the concentration of the solution.

Answer 2

Answer:

resistance of a conductor depends on nature of the material,

Step-by-step explanation:

cross sectional area and length of the conductor
