*Question T5D05:
What is the resistance of a circuit for which the applied voltage is 12 volts and the current flow is 1.5 amperes?*  

*Correct Answer is  C: 8 ohms*  

### AI Response: (may contain errors)  

To find the resistance of a circuit, we can use Ohm's Law, which states:

$$
V = I \times R
$$

where:
- $V$ = voltage in volts
- $I$ = current in amperes
- $R$ = resistance in ohms

We can rearrange this formula to solve for resistance:

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

Now, substituting the given values:

- $V = 12$ volts
- $I = 1.5$ amperes

We calculate the resistance as follows:

$$
R = \frac{12 \text{ volts}}{1.5 \text{ amperes}} = 8 \text{ ohms}
$$

### Explanation of the Correct Answer:
- The correct answer is **8 ohms** because we applied Ohm's Law correctly with the given voltage and current values.

### Explanation of Incorrect Choices:
- **A: 18 ohms**  
  This would imply a higher resistance than calculated. If we used $R = \frac{12}{0.67}$ (which is incorrect), we would get 18 ohms, but this does not match our values.

- **B: 0.125 ohms**  
  This would suggest a very low resistance, which is not consistent with the given voltage and current. If we mistakenly calculated $R = \frac{12}{96}$, we would arrive at this incorrect value.

- **D: 13.5 ohms**  
  This value does not correspond to any correct application of Ohm's Law with the given voltage and current. It could arise from a miscalculation, such as using an incorrect current value.

### Summary:
- Use Ohm's Law to find resistance: $R = \frac{V}{I}$.
- For this problem, $R = \frac{12 \text{ volts}}{1.5 \text{ amperes}} = 8 \text{ ohms}$ is the correct calculation.
