Colour code carbon resistance consist of

Correct answer: A. Four bands read from left to right

  • A. Four bands read from left to right
  • B. Three bands read from left to right
  • C. Four bands read from right to left
  • D. None of these

Explanation

The color code for carbon resistors consists of four bands that are read from left to right. These bands represent the resistance value (first two bands), the multiplier (third band), and the tolerance (fourth band).

About Current Electricity

Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
