*Question T5D09:
What is the current through a 24-ohm resistor connected across 240 volts?*  

*Correct Answer is  C: 10 amperes*  

### AI Response: (may contain errors)  

To find the current through a resistor, we can use Ohm's Law, which states:

$$I = \frac{V}{R}$$

where:
- $I$ = current in amperes (A)
- $V$ = voltage in volts (V)
- $R$ = resistance in ohms (Ω)

In this case, we have:
- $V = 240$ volts
- $R = 24$ ohms

Now, substituting the values into the formula:

$$I = \frac{240 \text{ V}}{24 \text{ Ω}} = 10 \text{ A}$$

This shows that the current through the 24-ohm resistor connected across 240 volts is indeed 10 amperes, which is the correct answer.

### Explanation of Choices:
- **Choice A: 24,000 amperes**
  - This value is incorrect because it suggests an unrealistic current based on the given voltage and resistance. The calculation does not support such a high current.

- **Choice B: 0.1 amperes**
  - This value is too low. It may result from a miscalculation, possibly confusing the resistance or voltage values.

- **Choice C: 10 amperes**
  - This is the correct answer, as shown in the calculation above.

- **Choice D: 216 amperes**
  - This value is also incorrect. It does not align with the calculations based on Ohm's Law and suggests a misunderstanding of the relationship between voltage, current, and resistance.

### Summary:
- Use Ohm's Law to calculate current: $I = \frac{V}{R}$.
- For this problem, the current through a 24-ohm resistor at 240 volts is 10 amperes.
