🔍 Key Concepts

• Identify the semiconductor symbol in figure 8 (note the single emitter and two bases B1 and B2). • Recall the typical applications of a unijunction transistor (UJT), especially how it behaves in a relaxation oscillator. • Match the phrase "stable voltage and low current while operating" to the type of circuit that needs a predictable triggering or timing point rather than power amplification.

💭 Think About

• First, decide what kind of device is shown in figure 8: is it meant for power handling, linear amplification, or triggering/timing? • Look at each answer choice and ask: does this application mainly need high power and current, or a precise, repeatable trigger/threshold at relatively low current? • Think about which circuits require a device that repeatedly switches ON at a nearly constant voltage to charge and discharge a capacitor on a regular schedule.

✅ Before You Answer

• Be sure you can name the device represented by E, B1, and B2 terminals before choosing. • Eliminate any answer that clearly involves continuous power amplification or supplying significant load current, since the device operates at low current. • Choose the option whose circuits are known for using a relaxation oscillator or trigger device rather than a main power-carrying element.
