Imp

IMP, or Impedance, is a measure of how much a circuit resists or opposes the flow of electrical current. Think of it like the resistance in a pipe that restricts water flow, but for electricity. Unlike simple resistance, impedance also includes how a circuit reacts to alternating current (AC), which can involve energy stored in components like capacitors and inductors. Impedance is expressed in ohms (Ω) and helps engineers design circuits by understanding how different components interact with specific signals, ensuring proper operation and efficiency.
