Below are the topics and sub-topics in Class 10 Science Chapter 12:

• 12.1: Electric Current and Circuit

• 12.2: Electric Potential and Potential Difference

• 12.3: Circuit Diagrams

• 12.4: Ohm's Law

• 12.5: Factors in Which the Resistance of a Conductor Depends

• 12.6.1: Resistors in Series

• 12.6.2: Resistors in Parallel

• 12.7: Heating Effect of Electric Current

• 12.8: Electric Power

2. Why are coils of electric toasters and electric irons made of an alloy instead of any pure metal?

A. Coils of electric toasters and electric irons made of an alloy instead of a pure metal because the melting point of an alloy is much higher than a pure metal due to its high resistivity. Alloys do not melt at high temperatures. Hence, alloys are always used in heating appliances such as electric toasters and electric irons etc.
