If you increase the voltage of an electric circuit, what happens to the current?
In a simple circuit with a fixed resistance, when you increase the voltage, the current flowing through the circuit also increases. This relationship is known as Ohm's law, which states that current (I) is directly proportional to the voltage (V) and inversely proportional to the resistance (R): I = V/R. Therefore, if voltage increases and resistance stays the same, the current must also increase.
When you increase the voltage of an electric circuit, the current generally increases as well, provided that the other factors in the circuit remain constant. This relationship between voltage and current is known as Ohm's Law. Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across it, and inversely proportional to the resistance (R) of the conductor.
Mathematically, this relationship can be expressed as:
I = V / R
Where I represents the current in the circuit, V represents the voltage applied, and R represents the resistance.
Given this equation, it is clear that an increase in voltage (V) will result in an increase in current (I), as long as the resistance (R) remains constant. This is because there is a greater potential difference pushing the charged particles (electrons) through the circuit, resulting in a higher rate of flow of electric charge. However, if the resistance increases while the voltage remains the same, the current will decrease.
