Ohm’s Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across it and inversely proportional to its resistance (R), provided the temperature remains constant.
The relation is:
V = I × R
Here’s how each factor depends on the others:
• If voltage (V) increases, current (I) also increases (when resistance is constant).
• If resistance (R) increases, current (I) decreases (when voltage is constant).
• If current (I) increases, voltage (V) also increases (when resistance is constant).
In simple terms:
– Voltage pushes the current.
– Resistance opposes the current.
– Current is the flow caused by voltage and limited by resistance.
