Answer / zan

In electrical engineering, load factor is the average power
divided by the peak power, over a period of time. The peak
may be a theoretical maximum, rather than a measured
maximum.
In the electricity industry, load factor is a measure of
the output of a power plant compared to the maximum output
it could produce.
The two commonest definitions are:
• the ratio of average load to capacity
• The ratio of average load to peak load in a period.
Assuming the first definition, a higher load factor is
better:
• A power plant may be less efficient at low load
factors.
• A high load factor means fixed costs are spread
over more kWh of output.
• A high load factor means greater total output.

Answer / p.subash

Load factor for a power plant is the ratio between average
load and peak load and can be expressed as
μlf = (100) Pal / Ppl
where
μlf = load factor (%)
Ppl = peak load for the power plant in the period (kW)

If a 1.5V,3W torch light bulb is connected in series with a 15HP/11.19KW,230V single phase motor and the combination is connected against a 230V supply and switched on than what will happen keeping all other parameters as it should be A)the bulb will glow normally B)the bulb will not glow C)the bulb will glow with extra brightness D)the bulb will burn out and if a fuse is connected to the above circuit will something happen to the fuse and what about the single phase motor will it be affected? Please explain with derivation
