What is k factor?
K-factor is a weighting of the harmonic load currents according to their effects on transformer heating, as derived from ANSI/IEEE C57.110. A K-factor of 1.0 indicates a linear load (no harmonics). The higher the K-factor, the greater the harmonic heating effects.
Why does a switch make a light turn on and off?
The purpose of a switch is to stop and start a current flow in a circuit. The stopping of a current flow in a circuit effects the load of the circuit by stopping its action. Resuming the current flow in a circuit also resumes the action of the load.
What is the effect of load factor and diversity factor on cost of generation in a power station?
Load factor effects the cost of generation. Higher the load factor higher will be the average load. So no. of units generated for a given period of time for the same max. demand will be more. Therefore, overall cost per unit of electrical energy decreases due to distribution of standing charges which are proportional to the max. demand and independent of units generated. Diversity factor effects the cost of generation. More is the diversity lesser will be max. demand due to which installation capacity of plant will be less. Lesser is the installation capacity lesser will be the capital required for installation. So lesser will be generation cost. And the fixed charges in the tariff would be less.
What is difference between floating load and ground load?
In case of grounded load load is grounded and voltage is measured across it. while in case of floating load load is not grounded instead it is connected in feedback circuit.
How does load current varies with the load resistance?
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.
