Question
e) dielectric f) kilowatt-hour K) ohm I EMF DIRECTIONS: Are the following statements true about a)series oncuits, b) parallel circuits, c) neither, or d) both? 50. The current in any load equals the voltage across that load divided by its resistance. 51. The voltage on all loads is the same. 52. A short across one load increases the voltage on the others. DIRECTIONS: In the system below, match the described trouble to the most probable causes. 53. Contact TR1 do not close 54. M1 runs, but does not seal in 55. M1 will not shut off a) Coil M1 is open. b) LS1 and LS2 are not being activa c) P81 or CR1 or TR1 is shorted. d) LS3 or LS4 is not being activaters e) One of the OL's is tripped. f) Auxiliary contacts M1 are bad.Explanation / Answer
50) Given that the current I = voltage/ Resistance = V/R
It is same for any circuit.so answer is d.( Both)
51) In parallel circuits only the voltages are same.so the answer is b.
52) In the circuit the sum of all voltages must be zero. In the parallel circuits the voltage must be same. The voltage short and more only happens in the series circuits. So if the votage short at any series ciruits load leads to voltage rise on another load.
