State whether the following statements are true or false.
a. An electric motor converts mechanical energy into electrical energy.
b. An electric generator works on the principle of electromagnetic induction.
c. The field at the center of a long circular coil carrying current will be parallel straight lines.
d. A wire with green insulation is usually the live wire of an electric supply.
An electric motor converts electrical energy into mechanical energy.
An electric generator is a device that generates electricity by rotating a coil in a magnetic field.
A long circular coil is a solenoid. The magnetic field lines inside a solenoid are parallel straight lines.
Live wires have red insulation cover, while the earth wire has green insulation.Answered by Shivani Kumari | 2 years ago
State the rule to determine the direction of an
(i) magnetic field produced around a straight conductor carrying current,
(ii) force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it, and
(iii) current induced in a coil due to its rotation in a magnetic field.
