If the circuit's resistance is increased the current will increase.
If the circuit's resistance is increased the current will increase.

If the circuit's voltage is increased the current will increase.
If the circuit's voltage is increased the current will increase.

If the circuit's voltage is increased the current will decrease.
If the circuit's voltage is increased the current will decrease.

If the circuit's resistance is increased the current will decrease.

Answer 1

According to Ohm's Law, the relationship between current (I), voltage (V), and resistance (R) is defined by the formula:

\[ I = \frac{V}{R} \]

Based on this equation, the following statements can be evaluated:

1. **If the circuit's resistance is increased, the current will increase.**
- **Incorrect**: Increasing resistance (R) decreases the current (I) if voltage (V) remains constant.

2. **If the circuit's voltage is increased, the current will increase.**
- **Correct**: Increasing voltage (V) while keeping resistance (R) constant will increase the current (I).

3. **If the circuit's voltage is increased, the current will decrease.**
- **Incorrect**: Increasing voltage (V) increases current (I) if resistance (R) remains constant.

4. **If the circuit's resistance is increased, the current will decrease.**
- **Correct**: Increasing resistance (R) decreases current (I) if voltage (V) remains constant.

So, the correct statements are:

- If the circuit's voltage is increased, the current will increase.
- If the circuit's resistance is increased, the current will decrease.
