Class 7 Chapter 14 Electricity Quiz

Electric Current

• The unit of electric current is the Ampere (A)
• Electric current is the flow of electrons from high to low potential

Conductors of Electricity

• Copper is a good conductor of electricity
• Other materials like gold, aluminum, and iron are also good conductors

Resistance and Resistors

• When an electric current passes through a resistor, energy is converted into heat
• The resistor opposes the flow of electric current and reduces the voltage
• The amount of resistance depends on the material, length, and cross-sectional area of the resistor

Test your knowledge of electricity and its circuits with this quiz on Class 7 Chapter 14. Answer questions on the unit of electric current, conductors of electricity, and the effect of electric current passing through a resistor.
