remember guys and gentlemen it is all about measurement of resistance in circuits according to what is voltage you are to be given in circuit and resistor is the property or element of the circuit proportional to the voltage applied with resistor is known as resistance. resistance tells us how much current should have to flow in circuit or to other components in the circuit and limits the electron flow in circuit.however,in-short i say HIGH RESISTANCE MEANS low current flow depending about material of resistance or diameter of resistor and its length of wire,thickness of wire in circuit what you have for?
LOW RESISTANCE MEANS high current flow in circuit it is easy passage for electron to flow without collision in track.so,electron must encounter with resistor so the resistor should work properly.in practical and real world resistor never get shorted.resistor may considered open or high resistance these fault create in electronics world.

if i get a drop in my 1st year and the i clear my 2nd year and 3rd year all clear and i dont have any back logs so can i be able to sit in campus selection??

1. A 380 / 220 V r.m.s. 3-phase 4-wire circuit carries loads of 8 + j8.1 ohm; 4 + j4.1 ohm; and 2 +j2.1 ohmin the three phases respectively. The length of the circuit is 100 m, and the resistivity of the phase conductors is 0.0005 Ω/m. The neutral conductor is of the same size as the phase conductors. a) Select a reference angle 0for the first phase. Then write down the three phase voltages in both polar format and complex number format. b) Make appropriate assumptions, and take temperature effects on resistance is insignificant. Calculate the currents in the three phases. (Note: Determine conductor resistance, and apply Kirchhoff’s Voltage Law) Based on the result, suggest a main switch rating for the circuit. c) Show your preferred direction of neutral current in a diagram, and then determine its value. (Note: Apply superposition principle, and Kirchhoff’s Current Law) Use its magnitude to show that in this circuit, the unbalanced load may increase the voltage drop in some of the phases. (Note: Also observe the common volt drip in neutral) State your assumptions, if there are any. d) Suddenly the neutral wire of the circuit is broken. Estimate the new currents in the first phase, i.e. Phase L1. State your assumptions, if there are any.
