FAQs on Current Electricity Video Lecture - Physics for GCSE/IGCSE - Class 10
| 1. What is the difference between AC and DC current? |  |
Ans. Alternating Current (AC) flows in one direction and then reverses, while Direct Current (DC) flows consistently in one direction only.
| 2. How is current measured in a circuit? | |
Ans. Current is measured in a circuit using an ammeter, which is placed in series with the component or load being measured.
| 3. What is Ohm's Law and how is it used in current electricity? | |
Ans. Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance. It is used to calculate current, voltage, and resistance in a circuit.
| 4. How does a circuit breaker work to protect against overcurrent? | |
Ans. A circuit breaker works by automatically interrupting the flow of current in a circuit when it detects an overcurrent condition, thus preventing damage to the circuit and devices connected to it.
| 5. What are some common sources of electrical resistance in a circuit? | |
Ans. Some common sources of electrical resistance in a circuit include wires, connectors, switches, and the components themselves.
