Answer 1

Ohm's Law states that the current (I) in a circuit is directly proportional to the voltage (V) across it and inversely proportional to the resistance (R) in the circuit. This relationship is mathematically expressed as:

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

From this equation, we can determine the effects of voltage and resistance on current:

1. **If the circuit's resistance is increased, the current will decrease.**
- This is true because, with a constant voltage, increasing resistance will reduce the current.

2. **If the circuit's voltage is increased, the current will increase.**
- This is also true because, with a constant resistance, increasing the voltage will raise the current.

So the correct responses are:
- "If the circuit's resistance is increased, the current will decrease."
- "If the circuit's voltage is increased, the current will increase."
