‘The potential difference between two conductors is 1 volt.’ Explain the meaning of this statement.
State whether the resistance of filament of a bulb will decrease, remain unchanged or increase when it glows.
State the relation between electric current; the number of electrons moving in a circuit and time in seconds.
What do you understand by the term electric resistance?
The following Figure represents a negatively charged gold Ieaf electroscope. Label the parts, P, Q, and R and the estate whether each is an insulator or a conductor. Also, indicate the distribution of charges on the system in the diagram.
The following figure shows a metal rod PQ mounted on an insulated stand. The cap of an uncharged electroscope touches one end Q of the metal rod. A negatively charged ebonite rod is brought near the other end P of the metal rod.
(a) What charge does the end P have?
(b) What charge does the end Q have?
(c) What charge does the cap of the electroscope have?
(d) What charge does the gold leaf have?
(e) Will the leaf diverge or collapse? Give reason.
(f) If the electroscope is now earthed, what charge does the metal rod have?
