Answer

1. **b) Battery** A battery is a source of electrical energy, converting chemical energy into electrical energy. Wires conduct electricity, switches control the flow, and bulbs convert electrical energy into light and heat. 2. **c) Ammeter.** An ammeter is specifically designed to measure current. While a "current meter" might seem correct, the standard term used is "ammeter." 3. **c) To change the amount of current in the circuit.** Resistors impede the flow of current. They don't transform voltage into current (though changing resistance affects current given a fixed voltage), provide energy, or primarily convert electrical energy to other forms (though some energy is lost as heat). 4. **c) Current is the same in series circuits and voltage is the same in parallel circuits.** This is a fundamental principle of circuit analysis. In a series circuit, the current has only one path to follow, so it's the same throughout. In a parallel circuit, each branch connects directly to the voltage source, ensuring equal voltage across each branch. 5. **c) 𝑉=𝐼𝑅** Ohm's Law states Voltage (V) equals Current (I) multiplied by Resistance (R). 6. **a) Light bulb** A light bulb is a load, not a source. It consumes electrical energy, converting it into light and heat. Cells, batteries, and electrical outlets are all sources of electrical energy.
