SSC JE Electrical 2019 with solution SET-2 Observe the given figure. Find Thevenin’s resistance as seen from open-circuited terminals? 16 Ω 4 Ω 8 Ω 32 Ω 16 Ω 4 Ω 8 Ω 32 Ω ANSWER EXPLANATION DOWNLOAD EXAMIANS APP To find the Thevenin’s resistance the current source is open-circuited and the voltage source is short-circuited.
SSC JE Electrical 2019 with solution SET-2 If a zero-centered voltmeter has a scale from 5V to − 5V, then the span of it is 5 V 10V −5 V 0 V 5 V 10V −5 V 0 V ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Voltage Scale Span of instrument = Vmax − VminGivenVmax = 5 VVmin = −5VSpan = 5 −(−5) = 10 V
SSC JE Electrical 2019 with solution SET-2 A diode appears as in forward region of its characteristics? A high resistor An OFF switch A capacitor An ON switch A high resistor An OFF switch A capacitor An ON 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.
