Final answer:
Adding resistors in parallel with a battery increases the current due to a decrease in the overall resistance of the circuit, maintaining the voltage across unchanged resistors and doubling the voltage across a fixed resistor results in double the current.
Step-by-step explanation:
When resistors are connected in parallel with a battery, the current being drawn from the battery typically increases. This is because the addition of parallel resistors decreases the overall resistance of the circuit which allows more current to flow from the battery according to Ohm's law. Therefore, the correct answer is a) Increases.

- If two identical resistors are connected in parallel and the resistance of one is increased, the current through and the voltage across the unchanged resistor remains the same, keeping the conditions of the other components constant, so the answer would be a)
- If the voltage across a fixed resistance is doubled, according to Ohm's law, the current will also double which makes the correct choice a).
- As for the energy stored in a circuit with capacitors, when you increase the number of capacitors connected in parallel, the energy stored increases since each capacitor can store a certain amount of energy. However, when capacitors are connected in series, the overall capacity decreases, and thus the stored energy decreases. So the correct answer is b) increases, decreases.
