1- XC and the RC time constant are both measures of the reaction of C to a change in ____? 2-The power factor is a numerical ratio with a value between 0 and 1 equal to the ______________ of the phase angle. 3-When V and I are out of phase because of reactance, the product of V times I is called ______________ power 4-For _____________ inductors, the branch currents can be added algebraically. 5- The ______________ power in watts can be calculated as I^2R 6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL 2*3.141592653*1kHz*30mH =188 ohms Please check) 7-A parallel RL circuit has the values, R = 5kohms, XL = 5kohms. A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.
hi can anyone pls tell me the eee interview core questions asked in l&t
please send the last 5 years {{{JUNIOR ENGINEER - ELECTICAL, ELECTRONICS RRB CHENNAI and secundrabad}}} TECHNICAL question papers TO MY EMAIL ID dinesh100701@gmail.com
1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
