GPT 3.5
Changes in voltage and resistance affect the current flow in a circuit according to Ohm's Law, which states that the current (I) flowing through a circuit is directly proportional to the voltage (V) applied across the circuit and inversely proportional to the resistance (R) of the circuit.
When the voltage applied to a circuit increases, the current flowing through the circuit also increases, assuming the resistance stays constant. This is because a higher voltage provides more energy to push the electric charges through the circuit.
Conversely, if the resistance in a circuit increases, the current flowing through the circuit decreases, assuming the voltage stays constant. This is because a higher resistance restricts the flow of electric charges, making it more difficult for current to pass through the circuit.
In summary, changes in voltage and resistance affect the current flow in a circuit in the following ways:
- An increase in voltage results in an increase in current flow.
- An increase in resistance results in a decrease in current flow.
