A bulb in a staircase has two switches , one at the ground floor and the other one at the first floor. The bulb can be turn ON and also OFF by any of the two switches irrespective of the state of the other switches, then what is the logic of switching of the bulbs

@lazyaditya Data is adequate and I am totally satisfied with the views of 'The Electrician' Also, your answer is true. thanks to both of you ...

thanks, jim

please suggest me simple and pecise notes or book for the above that can provide full concept in a very short span of time perhaps this is not the homework.

Homework Statement a 4 kva, 230/115 volt, 400 HZ, single phase transformer originally designed for use in air crafts, is available in a laboratory for obtaining 115 volt supply from standard 230 volt,50 HZ mains if overloading of the device is not permitted then net kva output is...Homework...

Homework Statement the voltage Vc in the figure is always equal to 2 Relevant equations The Attempt at a Solution From kirchhoffs law, -Vc+4+5=0 Vc=9 V will Vc always equal to 9 V or it will vary?

Homework Statement The number of 2 uF, 400 V capacitors is needed to obtain a capacitor value of 1.5 uF rated for 1600 V is..... Homework Equations The Attempt at a Solution equating the energy on both sides, 1/2*2*400^2*n=1/2*1.5*1600*1600, n=12, here n = number of capacitors...

RLC circuit @BvU Since the voltage across inductor is equal to the voltage across the capacitor in magnitude, but out of phase by 180 degrees, jwl*i = -(j/(wc))*i Here i = current, w = frequency, c = capacitor and l = inductor Does the maximum voltage across inductor occurs slightly below...

@BvU, Can you explain in a better way what did you mean by putting in 2?

Homework Statement in series rlc circuit maximum voltage across inductor occurs at which frequency?Homework Equations The Attempt at a Solution In the series rlc circuit current through the inductor is maximum at the resonance frequency. But I don't know whether at resonance frequency maximum...

Homework Statement A current i(t) as shown in the figure is passed through a capacitor. the charge (in micro coulomb) acquired by the capacitor after 5 micro seconds Homework Equations here slope is given for 3 microsecond ie. current=dq/dt = 2.5 charge upto here = 3*2.5=7.5 micro...
