What is the unit of measurement for electrical voltage?
Answer: The volt. Voltage is measured in volts (V), named after the Italian physicist Alessandro Volta. It represents the difference in electrical potential between two points in a circuit.
In which type of circuit are the components connected one after another?
Answer: A series circuit. In a series circuit, the components are connected one after another, forming a single loop. The same current flows through every component.
Which of the following materials is the best conductor of electricity?
Answer: Silver. Silver is the best electrical conductor of all the metals. However, because of its high cost, copper is the metal most widely used in electrical installations.
What is the standard voltage of household sockets in France?
Answer: 230 volts. The standard voltage of household sockets in France is 230 volts (since European harmonisation). In the United States, household voltage is 120 volts.
What is the unit used to measure the electrical energy consumed by households?
Answer: The kilowatt-hour. The kilowatt-hour (kWh) is the unit used to measure the electrical energy consumed by households. One kWh is the energy used by a 1,000-watt appliance running for one hour.
