Find Norton equivalent current to the left of terminals x-y in Figure.
Detailed Solution for MPPGCL JE Electrical Mock Test - 6 - Question 9

The Norton current IN is the current that flows through the short-circuited terminals x-y. With x-y terminals short-circuited, the resistance RT offered to 18 V source is
RT = 200+(800||200) = 200+160=360Ω
∴ Circuit current,
I = V/RT = 18V/360Ω = 0.05A
∴ Norton current, IN = Current in 800Ω resistor

The value of demand factor is-
Detailed Solution for MPPGCL JE Electrical Mock Test - 6 - Question 14
The word “demand” itself says the meaning of Demand Factor. The ratio of the maximum coincident demand of a system, or part of a system, to the total connected load of the system.

  • Demand Factor = Maximum demand / Total connected load

  • For example, an oversized motor 20 Kw drives a constant 15 Kw load whenever it is ON. The motor demand factor is then 15/20 =0.75= 75 %.

  • Demand Factor is expressed as a percentage (%) or in a ratio (less than 1).

  • Demand factor is always < =1.

Hence, the correct option is (A)
