example 2.2   
 
 (a)   
maximum demand of consumer A =1.100000kW 
 
demand factor of consumer A =0.440000 
 
maximum demand of consumer B =1kW
 
demand factor of consumer B = 0.333333 
 (b)   
The variation in demand versus time curves are plotted and shown in Fig This is known as chonological load curve. 
 (c)   
maximum demand of the group is 1100Wgroup diversity factor = 1.909091 
 (d)   
energy consumed by A during 24 hours is =5500Wh
it is seen that energy consumed by A is equal to the area under the chronological load curve of A 
 energy consumed by B during 24 hours is300x1+100x2+200x8+600x5=6900Wh 
 (e)   
maximum energy which A could consume in 24hours = 26.40kWh 
maximum energy which B consume in 24 hours is =24.00kWh 
 (f)   
actual energy/maximum energy
for A = 5500/26400 =0.208333 
for b =6900/24000 =0.287500
