Shunt reactors are sometimes used in high voltage transmission system to

The closed loop transfer function of a system is $T\left(s\right)=\frac{4}{\left(s^2+0.4s+4\right)}$. The steady state error due to unit step input is ________.

The state transition matrix for the system ≤ft[ {*20c {x_1}\\ {x_2} } ] = ≤ft[ {*20c 1&0\\ 1&1 } ] ≤ft[ {*20c x_1\\ x_2 } ] + ≤ft[ {*20c 1\\ 1 } ]u is

The saw-tooth voltage waveform shown in the figure is fed to a moving iron Voltmeter. Its reading would be close to –

While measuring power of a three phase balanced load by the two – wattmeter method, the readings are 100 W and 250 W. The power factor of the load is –
