Frequently Asked Questions (FAQs)

Q1: What is the definition of electric current? Ans: Electric current is the rate of flow of net charge through any cross-section of a conductor. Its SI unit is the Ampere (A). Q2: What does Ohm’s Law state? Ans: Ohm’s Law states that the current passing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and physical state remain constant. Q3: What is the difference between Resistance and a Resistor? Ans: Resistance is the property of a material that opposes the flow of current, while a Resistor is a physical component designed to provide a specific amount of resistance in a circuit. Q4: How does voltage behave in a parallel circuit? Ans: In a parallel circuit, the voltage across each component or resistor remains exactly the same; it does not divide among the branches. Q5: What is the formula for Joule’s Law of Heating? Ans: Joule’s Law states that the heat produced in a resistor is equal to the product of the square of the current ($I^2$), the resistance ($R$), and the time ($t$), given by the formula $H = I^2Rt$.
