Examples and Assignments
1. A heavy duty battery of a truck maintains a current of 3A for 24 hour. How much charge flows from the battery during this time?
2. While analyzing a circuit the internal resistance of e.m.f. sources are ignored why?
If aluminum and copper wires of the same length have the same resistance, which has the larger diameter?
3. Why?
4. Under what circumstances can the terminal P.D. of a battery exceed its e.m.f.?
5. What is the difference between an e.m.f. and a P.D.?
6. How the loop rule and junction rule are based on the conservation of energy principle?
7. Why rise in temperature of a conductor is accompanied by a rise in the resistance?
Does the direction of e.m.f. provided by a battery depend on the direction of current flow through the
8. battery?
9. Voltages are always measured between two points. Why?
10. Is every emf a potential difference? Is every potential difference an emf?
11. How much charge flow in pocket calculator each minute when the current is 0.0001A?
When Wheatstone Bridge is balanced, then no
12. current flows through the galvanometer, why?
