What is ohmic drop?

Ohmic drop, also known as voltage drop, refers to the reduction in voltage across a conductor or circuit element due to its resistance when current flows through it. This phenomenon is described by Ohm's Law, which states that voltage (V) is equal to the product of current (I) and resistance (R) (V = IR). It is significant in electrical systems because it can lead to inefficiencies and power loss, particularly in long transmission lines or low-resistance components. Understanding and managing ohmic drop is essential for optimizing circuit performance and ensuring proper operation of electrical devices.
