Using Euler’s method, find an approximate value of y corresponding to x = 0.4 given that
and y(0) = 1. Use a step size of 0.1.

An FM signal has a carrier swing of 100 kHz when modulating signal has a frequency of 8 kHz. The modulation index is

The solution of the differential equation sin x is

A current of 20 A gives full scale deflection if measured by a dynamometer ammeter. The current through the meter when it reads one-fourth of the scale is:

A current transformer is never operated with its secondary open circuited because:

A 3-phase load having 3 resistors of equal value (1 in each phase) connected in star if connected to a 3-phase supply draws power ‘P’ from the supply. If one of the resistor is removed, then power drawn will be

Two wattmeter method is used for measuring power of a three-phase load. If one of the wattmeter shows negative reading then power factor angle could be

A single transistor is operating as an ideal class B amplifier with a 1kΩ load. A dc meter in the collector circuit reads 10mA . The signal power delivered to the load is

A signal  is applied to a system with transfer function  then the steady state output is

A transmission line is having 30% series compensation. This series compensation will give ________% increment in ideal power transfer capacity (approx.).

An amplifier has a mid-frequency gain A₀ = 100, an upper cut-off frequency f_H = 40 kHz, and a lower cut-off frequency f_L = 20 Hz. For a feedback transfer ratio β= 0.1, find the upper cut-off frequency with negative feedback.

What is the upper trigger point of the circuit shown.

The fundamental period of discrete time signal is
