FAQs on Current Electricity JEE Main 2025-26: Mock Test Practice and Preparation
1. What is current electricity?
Current electricity refers to the flow of electric charge (mainly electrons) through a conductor, such as a wire. This flow occurs due to a potential difference (voltage) applied across the conductor, and it is measured in amperes (A).
2. How is electric current measured?
Electric current is measured in amperes (A) using a device called an ammeter. The ammeter is connected in series with the circuit to measure the rate of flow of charge per second.
3. What is Ohm's Law?
Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the potential difference (V) across its ends, provided the physical conditions remain constant. It is mathematically expressed as V = IR, where R is the resistance of the conductor.
4. Define resistance and its unit.
Resistance is the opposition offered by a material to the flow of electric current. Its SI unit is the ohm (Ω). Good conductors have low resistance, whereas insulators have high resistance.
5. What factors affect the resistance of a conductor?
Resistance depends on:
• Length (L) – resistance increases with length.
• Cross-sectional area (A) – resistance decreases with increasing area.
• Nature of material – different materials have different resistivities.
• Temperature – for most conductors, resistance increases with temperature.
6. What is electric power and its formula?
Electric power is the rate at which electric energy is consumed or converted in a circuit. Its SI unit is the watt (W). It is given by P = VI, where V is voltage and I is current. Alternative formulas are P = I^2R and P = V^2/R.
7. What do you understand by resistivity?
Resistivity (or specific resistance) is a property of the material which determines how much it resists the flow of electric current. Its SI unit is ohm-meter (Ω·m). It depends only on the nature of the material and temperature, not on shape or size.
8. State Kirchhoff's laws for complex electrical circuits.
Kirchhoff's Laws:
• Kirchhoff's Current Law (KCL): The sum of currents entering a junction equals the sum of currents leaving it.
• Kirchhoff's Voltage Law (KVL): The sum of potential differences around any closed loop is zero.
9. How do you calculate the effective resistance of resistors in series and parallel?
For series: Total resistance, R = R₁ + R₂ + R₃ + ...
For parallel: 1/R = 1/R₁ + 1/R₂ + 1/R₃ + ...
Use these rules to simplify circuits in NEET, CUET, EAMCET, and JEE exams.
10. What is the current electricity rate for households in Lucknow?
As of June 2024, the current electricity rate in Lucknow for domestic consumers generally ranges from around ₹5.50 to ₹7.50 per unit (kWh), depending on the consumption slab. Rates may vary by supplier, government policies, and usage; always check the latest updates from your local electricity board.
11. How is internal resistance of a cell determined?
Internal resistance of a cell is determined by connecting the cell to a known external resistance, measuring the terminal voltage for different currents, and applying V = E - Ir, where E is EMF, I is current, r is internal resistance, and V is terminal voltage.
12. Why are practice questions important for mastering current electricity concepts?
Solving practice questions enhances your conceptual clarity, problem-solving skills, and speed in topics like resistance calculation, Ohm's Law application, Kirchhoff's Laws, and circuit analysis. Regular practice helps to score better in competitive exams such as NEET, CUET, EAMCET, and JEE.
