FAQs on Current Electricity Mock Test 1 – 2025-26 Exam Preparation
1. What is current electricity?
Current electricity refers to the flow of electric charge (usually carried by electrons) through a conductor, such as a metal wire. The rate at which this charge flows is called electric current and is measured in amperes (A).
2. What is the formula for Ohm's Law?
Ohm's Law states that the current (I) passing through a conductor between two points is directly proportional to the voltage (V) across the two points, provided the temperature remains constant. The formula is: V = IR, where R is the resistance measured in ohms (Ω).
3. How is resistance different from resistivity?
Resistance (R) is the property of a material to oppose the flow of electric current, depending on length, area, and material of the conductor. Resistivity (ρ) is a material-specific constant that describes how strongly the material opposes current, independent of shape and size.
4. What are series and parallel circuits?
Series circuits connect components end-to-end, so the same current flows through all; the total resistance increases. Parallel circuits connect components across the same voltage, so each branch gets the full voltage; the total resistance decreases and current splits among the branches.
5. What is Kirchhoff's First Law (Junction Law)?
Kirchhoff's First Law, also called the Junction Law, states that the algebraic sum of currents entering a junction is zero. This is based on the conservation of charge—current entering equals current leaving.
6. What is drift velocity in current electricity?
Drift velocity is the average velocity with which free electrons move in a conductor when an electric field is applied. It is responsible for the flow of current in metallic conductors.
7. What are the factors affecting the resistance of a conductor?
Resistance of a conductor depends on its length (R ∝ l), cross-sectional area (R ∝ 1/A), nature/material, and temperature. Longer conductors and higher temperatures mean greater resistance, while larger cross-sectional areas reduce resistance.
8. What is the SI unit of electric current?
Electric current is measured in amperes (A) in the SI system. One ampere is defined as the flow of one coulomb of charge per second.
9. How is internal resistance of a cell defined?
Internal resistance of a cell is the resistance offered by the electrolyte and the electrodes within the cell itself, causing a drop in the cell's terminal voltage when current flows.
10. What is the rate of current electricity in Lucknow?
The current electricity rate in Lucknow varies depending on usage (domestic, commercial, industrial) and may change over time. As of 2024, domestic rates usually range from ₹5 to ₹7 per unit (kWh). Please refer to the official Uttar Pradesh Power Corporation Limited (UPPCL) website for latest tariffs.
11. What are some important questions and practice topics for current electricity (NEET, JEE, CUET, EAMCET)?
Important practice topics include:
- Ohm's Law and circuit analysis
- Kirchhoff's Laws and their applications
- Wheatstone Bridge and meter bridge problems
- Cell and battery combinations (series/parallel)
- Resistivity and conductivity numericals
Focus on diagram-based questions, NCERT examples, and previous year papers for CBSE Class 12, NEET, JEE, CUET, and EAMCET.
12. Can you suggest a fun current electricity movie quiz for students?
Yes! Try this popular quiz format:
1. Name a movie character who discovers electricity.
2. Which sci-fi movie features a circuit malfunction as a key plot point?
3. Identify the movie where generators and circuit diagrams are part of a rescue scene.
Such themed quizzes make learning current electricity more engaging and help students relate concepts to popular culture.
