According to Ohm's Law, what is the relationship between current, voltage, and resistance?

Ohm's Law states that the relationship between current (I), voltage (V), and resistance (R) can be expressed with the formula V = I * R. This indicates that voltage is directly proportional to both current and resistance. In practical terms, this means if the current flowing through a conductor increases while resistance remains constant, the voltage across that conductor also increases. Similarly, if the resistance increases while the current stays the same, the voltage will also increase.

Understanding the relationship framed by Ohm's Law is crucial for analyzing electrical circuits and designing systems that function properly under given conditions. This formula helps predict how changes in one variable will affect the other two, which is foundational knowledge for anyone working in fields involving electricity, such as electrical engineering, physics, or surveying, particularly when dealing with electronic instruments in the field.
