FAQs on Worksheet: Household Circuits - Physics Class 10 ICSE
| 1. What are the main components of a household electrical circuit? |  |
Ans. The main components of a household electrical circuit include the power source (such as a battery or a mains supply), conductors (wires), load devices (like bulbs, fans, or appliances), and protective devices (such as circuit breakers or fuses). These elements work together to ensure that electricity flows safely and effectively to power devices in the home.
| 2. How is electrical safety maintained in household circuits? | |
Ans. Electrical safety in household circuits is maintained through the use of circuit breakers, fuses, and grounding systems. Circuit breakers automatically shut off the electrical supply in case of overload or short circuits, preventing potential fires. Fuses serve a similar purpose by melting and breaking the circuit when excessive current flows. Grounding provides a safe path for excess electricity to be diverted away from users and sensitive equipment.
| 3. What is the difference between series and parallel circuits in household wiring? | |
Ans. In a series circuit, all components are connected end-to-end, so the same current flows through each device. If one component fails, the entire circuit is interrupted. In contrast, in a parallel circuit, components are connected across common points, allowing the current to flow through multiple paths. If one component fails in a parallel circuit, the others continue to operate. This is why most household circuits are wired in parallel.
| 4. Why is the use of insulators important in electrical circuits? | |
Ans. Insulators are materials that do not conduct electricity and are crucial in electrical circuits to prevent unintended flow of current. They cover conductors, preventing short circuits and protecting users from electric shocks. Common insulating materials include rubber, plastic, and glass, which help ensure that electricity flows along the intended path without leakage.
| 5. What role do voltage and current play in household circuits? | |
Ans. Voltage, measured in volts, is the potential difference that drives electric current through a circuit. Current, measured in amperes, is the flow of electric charge. In household circuits, the voltage supplied by the power source determines how much current can flow, and this current is what powers electrical devices. Understanding the relationship between voltage and current is essential for ensuring that circuits are designed to safely handle the required load.
