Ohm's Law in circuits

Ohm's Law describes the relationship between voltage (electric pressure), current (flow of electricity), and resistance (opposition to flow) in a circuit. It states that voltage equals current multiplied by resistance (V = IR). This means that increasing voltage boosts the current if resistance stays constant, and higher resistance decreases the current for a given voltage. The law helps predict how circuits behave and is fundamental in designing and troubleshooting electrical systems. In essence, Ohm's Law links these three factors, making it easier to understand and control the flow of electricity in various applications.
