Understanding the difference is critical for structured exam questions: Series Circuit Parallel Circuit Only one path for current. More than one path (branches). Current ( ) Same at all points ( Splits between branches ( Voltage ( ) Shared across components. Same across each branch. Independence If one bulb breaks, all go out. Bulbs work independently. 3. Core Concepts and Vocabulary F2 Science Electricity Exercises | PDF - Scribd
Before attempting practice questions, you must understand the fundamental quantities that govern electrical circuits. 1. Electric Current ( all go out.
Identify the mistake: “A student connects a voltmeter in series with a bulb. What happens?” (Answer: Very little current flows because voltmeter has high resistance; bulb barely lights.)
Always convert current to Amperes (A) if given in milliamperes (mA) before calculating (
Explanation: Branch 2: V=9V, R=6Ω. I = 9/6 = 1.5A.
Before diving into the exercises, memorize these core formulas. They are the keys to solving almost every calculation question in this unit. (Current = Charge / Time) Voltage ( ): (Voltage = Work Done / Charge) Ohm's Law: (Voltage = Current Resistance) Series Resistance: Parallel Resistance: 📝 Part 1: Top Multiple-Choice Exercises Question 1: Electrostatics
