Frequently Asked Questions (FAQs)

Q1. Define Electric Current and its SI unit.

Electric Current is the flow of electric charge. Its SI unit is the Ampere (A).

Q2. State Ohm’s Law and write its mathematical expression.

Ohm’s Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across it, provided its temperature and other physical conditions remain constant. Mathematically, Ohm’s Law is expressed as: I = V / R, where I is the current in Amperes (A), V is the voltage in Volts (V), and R is the resistance in Ohms (Ω).

Q3. What is the difference between conductors, insulators, and semiconductors? Provide examples of each.

Conductors allow the flow of electric current with ease (e.g., copper).
Insulators do not allow electric current to flow easily (e.g., rubber).
Semiconductors have conductivity between that of conductors and insulators (e.g., silicon).

Q4. Explain the concept of resistance and how it depends on the dimensions and resistivity of a conductor.

Resistance (R) is a property of a conductor that opposes the flow of electric current. It depends on the dimensions (length and cross-sectional area) of the conductor and its resistivity (ρ) according to the formula: R = (ρ * L) / A, where L is the length and A is the cross-sectional area of the conductor.

Q5. Define resistivity and its unit. Explain the factors that affect the resistivity of a material.

Resistivity (ρ) is a material property that measures its inherent resistance to the flow of electric current. Its SI unit is Ohm-meter (Ω·m). Factors affecting resistivity include temperature, impurities, and crystal structure.

Q6. What is the temperature dependence of resistance for conductors and semiconductors?

For conductors, resistance generally increases with an increase in temperature.
For semiconductors, resistance decreases with an increase in temperature.
