The relationship between voltage and current resistance in a electrical circuit

Question

Accepted Answer

In an electrical circuit, Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor.

Ohm's Law states V = I * R, where V is voltage, I is current, and R is resistance.
If the voltage in a circuit increases, the current will also increase if the resistance remains constant.
If the resistance in a circuit increases, the current will decrease if the voltage remains constant.
The relationship between voltage, current, and resistance can be visualized using a water pipe analogy: voltage is the water pressure, current is the flow rate, and resistance is the pipe size.
For example, in a circuit with a 12V battery and a 4 ohm resistor, the current flowing through the circuit would be 3A (12V / 4 ohms = 3A).
