There are four consumers in Nizwa of electricity having different load requirements at different time. Consumer 1 has a maximum demand of 3 KW at 9 pm , a demand of 1.6 KW at 8 pm and a daily load factor of 15%. Consumer 2 has a maximum demand of 3 KW at 12 noon, a load of 1 KW at 8 pm and an average load of 500 W. Consumer 3 has a maximum demand of 6 KW at 5 pm, a load of 5 KW at 8 pm and a daily load factor of 25%. Consumer 4 has an average load of 1 KW and his maximum demand is 4 KW at 8 pm. Determine (i) The diversity factor (ii) The load factor and average load of each consumer (iii) The average load and load factor of the combined load. combined load factor=

There are four consumers in Nizwa of electricity having different load requirements at different time. Consumer 1 has a maximum
demand of 3 KW at 9 pm , a demand of 1.6 KW at 8 pm and a daily load factor of 15%. Consumer 2 has a maximum demand of 3 KW
at 12 noon, a load of 1 KW at 8 pm and an average load of 500 W. Consumer 3 has a maximum demand of 6 KW at 5 pm, a load of 5
KW at 8 pm and a daily load factor of 25%. Consumer 4 has an average load of 1 KW and his maximum demand is 4 KW at 8 pm.
Determine (i) The diversity factor (ii) The load factor and average load of each consumer (iii) The average load and load factor of the
combined load.
combined load factor=
A typical electric-powered car having a 4A, 20V battery was charged at constant current from 8am till 10pm. Determine: (i) What is
the cost of electricity to charge the battery? (ii) What is the actual efficiency of the battery? [Data given: electric cost =$ 48/Wh, and
assuming 60% battery (chemical energy) to electricity conversion, and 75% electrical to mechanical energy conversion].
