(i) What values are displayed by the teacher? |
(ii) Which terminal positive or negative of the cell \[{{E}_{1}}\] is connected at X in case (a) and how is \[{{E}_{1}}\] related to E? |
(iii) What is the advantage of using thick metallic strips to join wires in a potentiometer? |
Answer:
(i) Scientific temperament, responsibility, perseverance and dutifulness. (ii) The deflection in galvanometer is one sided and the deflection decreased, while moving from one end A of the wire to the end B, its imply that current in auxiliary circuit (lower circuit containing primary cell) decreases, while potential difference across A and jockey increases. This is possible only when positive terminal of the cell \[{{E}_{1}}.\] is connected at X and \[{{E}_{1}}>E.\] (iii) The resistance of thick metallic strips is extremely small and hence negligible.
