For a series circuit, add the resistances together:
A) They all turn off.B) They stay lit with the same brightness.C) They blink rapidly.D) They get dimmer. Section B: Short Answer & Structural Questions Q5. Circuit Diagram Analysis Imagine a circuit containing a
Cover the letter you want to find with your finger to reveal the correct formula. If you want to continue practicing, tell me:
are connected in a series circuit. What is the effective resistance? A) C f2 science electricity exercise top
Write T or F next to each statement.
1-F (conventional current flows + to – outside; electrons flow – to +), 2-F (parallel – each gets full voltage), 3-T, 4-T, 5-F (1 mA = 0.001 A)
The "friction" slowing the flow. Measured in Ohms (Ω) . 💡 Pro-Tip: Remember Ohm’s Law: V = I × R . 3. Series vs. Parallel Circuits Most exercises ask you to compare these two setups: Series Circuit Parallel Circuit Pathways Single loop Multiple branches Current Same everywhere Splits between branches Voltage Shared across components Same across all branches Failure One bulb out = all out One bulb out = others stay on 4. Common Exercise Pitfalls Ammeter Placement: Always connect in series . For a series circuit, add the resistances together:
Components are in a single path. If one bulb breaks, all go out.
If one bulb blows out, what happens to the other bulb? Explain your answer.
Like charges repel; opposite charges attract. 2. Electric Current and Voltage Electric Current ( If you want to continue practicing, tell me:
): The amount of electrical energy supplied per unit charge to move it between two points. Measured in Volts (V) using a voltmeter connected in . 3. Resistance (
(higher temperatures generally increase resistance). Question 2: Home Electrical Safety
Like charges repel each other, while unlike charges attract each other.
