FAQs on Quick Revision: Electric Current and Its effects Video Lecture - Science Class 7
| 1. What is electric current and how is it defined? |  |
Ans. Electric current is the flow of electric charge through a conductor. It is defined as the rate of flow of electric charge past a point in a circuit, typically measured in amperes (A).
| 2. What are the effects of electric current on the human body? | |
Ans. Electric current can cause various effects on the human body, ranging from mild tingling sensations to severe burns, muscle contractions, and even cardiac arrest or death, depending on the current strength and path through the body.
| 3. How does electric current affect conductors and insulators differently? | |
Ans. Electric current flows easily through conductors as they have many free electrons that can carry the charge. In contrast, insulators have few free electrons, so they offer high resistance to the flow of electric current.
| 4. Can electric current cause fires or explosions? | |
Ans. Yes, electric current can cause fires or explosions if there is a high amount of current flowing through a circuit that exceeds the capacity of the wires or components, leading to overheating and potentially igniting nearby flammable materials.
| 5. How can electric current be measured in a circuit? | |
Ans. Electric current can be measured in a circuit using an ammeter, which is placed in series with the circuit to measure the flow of current through the conductor. The ammeter is connected in such a way that all the current flowing through the circuit passes through it, providing an accurate measurement.
