FAQs on Introduction to Electric Circuit Video Lecture - Science Olympiad Class 8
| 1. What is an electric circuit? |  |
Ans. An electric circuit is a closed loop or pathway that allows electric current to flow through it. It consists of various components, such as resistors, capacitors, and conductors, which are connected in a specific arrangement.
| 2. What are the different types of electric circuits? | |
Ans. There are three main types of electric circuits: series circuits, parallel circuits, and combination circuits. In a series circuit, the components are connected in a single path, while in a parallel circuit, the components are connected in multiple paths. Combination circuits are a combination of series and parallel circuits.
| 3. How does an electric circuit work? | |
Ans. An electric circuit works by allowing the flow of electric current. When a voltage source, such as a battery, is connected to a circuit, it provides a potential difference that drives the flow of electrons. The electrons flow through the circuit, encountering resistance from components like resistors, and eventually return to the voltage source.
| 4. What is the role of a resistor in an electric circuit? | |
Ans. A resistor is a component in an electric circuit that opposes the flow of electric current. It is typically made of materials with high resistance, such as carbon or metal alloys. The resistor helps control the amount of current flowing through the circuit and also dissipates electrical energy in the form of heat.
| 5. How can I calculate the total resistance in a series circuit? | |
Ans. To calculate the total resistance in a series circuit, you simply add up the resistance values of all the components connected in series. For example, if you have three resistors with resistance values of 10 ohms, 20 ohms, and 30 ohms connected in series, the total resistance would be 10 + 20 + 30 = 60 ohms.
