This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t ...
In most operational amplifier (op amp) circuits, the resistor tolerance and resistor temperature coefficient determine the gain accuracy and gain temperature drift (Figure 1 shows a typical circuit).
