Observation

Part (a):     Candidates performance was fair. Majority of the candidates were able to correctly define electric potential.
Part (b):     Candidates performance was below average. Most candidates were able to state the reason why soft iron is used to produce permanent magnet.
Part (c)      Candidates performance was fair.
Part (d):     Performance was poor. Most candidates were unable to correctly solve the problem on conductivity of the wire.
Part (e):     Performance was poor. Most candidates were unable to correctly solve the problem on electrical circuit.

The expected answer is:

11.(a) Electric Potential (V)
Electric potential is the work done in bringing a unit positive charge from infinity to that point (against the electrical force of the field)                                                          

(b)  It readily/easily loses its magnetism.                                                                        

(c)   Relationship between resistivity and conductivity

Resistivity is the reciprocal of conductivity
