An a.c. voltage of peak value 20 V is connected in series with a silicon diode andload resistance of 500 Ω. If the forward resistance of diode is 10 Ω, find :

A resistor is connected across the terminals of a 20-microfarad capacitor which has been previously charged to a potential difference of 500 V. If the potential drops to 300 V in 0.5 min, calculate the resistance value.

A 100 Ω resistance and a capacitor of 100 Ω reactance are connected in series across a 220 V source. When the capacitor is 50% charged, the peak value of the displacement current is

using the fact that silicon diode has Is=10^-14 at 25 degree celcius annd Is increases by 15% per degree celcius rise in temperature. find the value of Is at 125 degree celcius.

A circuit with 5v connected to a 2kΩ resistor. Series to the 2kΩ resistor is connected a Silicondiode and a 1kΩ resistor in parallel. What is current through 2kΩ resistor?

hen a dc𝑑𝑐 voltage of 100 V100 V is applied to an inductor, a dc𝑑𝑐 current of 5 A5 A flows through it. When an ac voltage of 200 V200 V peak value is connected to inductor, its inductive reactance is found to be 20√3Ω203Ω. The power dissipated in the circuit is _______ W.JEE Main 2024 (06 Apr Shift 1)
