Be able to write the word equations for neutralization (Acid + Alkali →right arrow Salt + Water) and reactions with metals.
| Question | Typical Correct Answer | Explanation | |----------|----------------------|--------------| | 1. Which device measures potential difference? | B) Voltmeter | Ammeter measures current, ohmmeter measures resistance, galvanometer detects small currents. | | 2. In a series circuit with two identical bulbs, if one bulb blows, the other: | C) Goes out | The circuit is broken; current cannot flow. | | 3. Which material is best for a conductor? | A) Copper | Lowest resistivity among common metals (silver is better but expensive). |
A student connects a 12V battery to a circuit containing a 6Ω resistor. Calculate the current flowing.
If you want, I can tailor these answers precisely to the actual Chapter 9 content if you paste the workbook questions or a brief table of contents.
