The electronic type fuel quantity indicating system consists of a bridge circuit, an amplifier, an indicator, and which other component?

The correct answer is a tank. In an electronic fuel quantity indicating system, the components work together to measure and display the amount of fuel present in the tank. The tank serves as the physical container for the fuel and is integral to the system because it holds the fuel whose quantity is being measured.

The bridge circuit, consisting of resistive elements, helps in detecting the fuel level by varying with the float mechanism as fuel levels change. The amplifier boosts the signal from the bridge circuit for better accuracy. The indicator visually displays the fuel quantity to the pilot, allowing for real-time monitoring of fuel levels. However, without the tank, there would be no fuel to measure, making it a critical component in the overall system.

Understanding this relationship helps in grasping how fuel quantity is monitored and the role each component plays, reinforcing the importance of having a tank within an electronic fuel quantity indicating system.
