Explanation / Answer
1. The Earth's magnetic field is similar to the magnetic field of a BAR MAGNET.
2. The magnetic field lines from a long straight wire are circles around the wire.
3. The property of a material which determines if a material is a conductor or insulator is called RESISTIVITY.
4. The mathematical relationship between the voltage, current and resistance is called Ohm's Law.
5. The direction of the conventional current is the direction positive charges would move through the circuit.
6. The light bulb will light only if the circuit is complete.
7. The magnetic torque on a square loop is maximum when the normal of the loop is perpendicular to the magnetic field.
8. The time constant in an RC circuit determines how long it takes for the circuit to charge and discharge. Both of these.
