3.What is the voltage drop in a cell, and how is it related to the e.m.f. and terminal voltage?
- A.The voltage drop is the work done per unit charge inside the cell and equals the difference between e.m.f. and terminal voltage.
- B.The voltage drop is the terminal voltage of the cell and is always equal to the e.m.f.
- C.The voltage drop is the energy lost outside the cell due to external resistance.
- D.The voltage drop is the sum of the e.m.f. and terminal voltage of the cell.
-
4.A resistor of 6 Ω resistance is connected in series with another resistor of 4 Ω resistance. A potential difference of 20 V is applied across the combination. What is the current through the circuit and the potential difference across the 6 Ω resistor?
- A.Current = 1 A, Potential difference = 6 V
- B.Current = 2 A, Potential difference = 12 V
- C.Current = 3 A, Potential difference = 18 V
- D.Current = 4 A, Potential difference = 24 V
-
5.Which two factors influence the internal resistance of a cell?
- A.The color of the electrolyte and the size of the cell.
- B.The nature of the electrolyte and the area and separation of the electrodes.
- C.The voltage of the cell and the material of the container.
- D.The temperature of the cell and the external resistance.
