SSC JE Electrical 2019 with solution SET-2 A diode appears as in forward region of its characteristics? A capacitor A high resistor An ON switch An OFF switch A capacitor A high resistor An ON switch An OFF switch ANSWER EXPLANATION DOWNLOAD EXAMIANS APP A P-N junction acts as a voltage-controlled switch. During forward biasied the p-n junction diode acts like an ON switch. When reverse biased, it acts like an OFF switch.
