32. Define electric potential and state its SI unit.
33. State the characteristics of magnetic field lines.
Answers
Answer:
The electric potential is the amount of work energy needed to move a unit of electric charge from a reference point to the specific point in an electric field.
Its SI Unit is Joule per coulomb.
The characteristics of magnetic field lines are -:
i.Field strength is proportional to the line density.
ii.Field lines cannot cross.
iii.The field is tangent to the magnetic field lines.
Answer:
32. It is defined as, An electric potential is the amount of work needed to move a unit positive charge from a reference point to a specific point inside the field without producing any acceleration. Its SI unit is j/c=Volts.
33. The properties of magnetic field lines can be summarized by these rules: ... Magnetic field lines can never cross, meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.
