Current, measured in amperes (amps), is the flow of electric charge through a conductor. In cybersecurity and electronics, current determines how much power is supplied to devices and systems. Managing current is crucial to prevent overheating, power surges, or damage to sensitive equipment. Insufficient or excessive current can disrupt device operation or even cause failures. Understanding current is essential for designing secure and reliable hardware, protecting against electrical faults, and ensuring uninterrupted operation of critical systems.
