Why the efficiency of a transformer which supplies a pure capacitive load is zero?
The efficiency of a transformer supplying a pure capacitive load is zero because a purely capacitive load draws reactive power rather than real power. Transformers are designed to transfer real power, and when a load is purely capacitive, no real power is consumed; instead, the transformer merely provides the necessary reactive power to maintain the electric field in the capacitor. As a result, the output power is zero, leading to zero efficiency, since efficiency is defined as the ratio of output power to input power.
Why regulation of Transformer is negative value for Capacitive Load Explain?
Regulating a transformer with a capacitive load can lead to negative effects because capacitive loads tend to cause leading power factor conditions, which can result in voltage rise and instability in the system. The regulation of the transformer, designed for inductive loads, may not adequately accommodate these conditions, leading to overvoltage issues. Additionally, the reactive power generated by capacitive loads can cause the transformer to operate inefficiently, potentially leading to overheating and reduced lifespan. Overall, the mismatch between transformer design and capacitive load characteristics can lead to operational challenges and reduced performance.
What is Pure Resistive?
A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.
What is non-inductive load?
non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.
Is tube light capacitive load?
no
Is a transformer load inductive or capacitive?
A transformer is fundamentally a set of coils; therefore, a transformer is an inductive load. However, by "transformer load", you seem to mean "the load that is connected to a transformer". Whether that load is inductive or capacitive depends mostly on what is hooked up to the transformer.

Would a computer be considered a capacitive load?
No because the very first component in the power supply is a transformer, which makes for it being an inductive load.
Does low load in transformer lead to low power factor?
Power factor is determined by the nature (resistive, inductive, capacitive) of a load, not whether it is a low load or a high load.
Why the load voltage increases when the load used is capacitive?
capacitive reaction

Why the capacitive voltage transformer and voltage transformer both are used in a substation?
three phases
Why the output voltage of transformer increases when capacitive loading is used?
if the load is capacitance then reactive power is injected in the circuit, as we know that reactive power is directly proportional to the voltage, if there is increase in reactive power automatically voltage at load end of the tranformer is increases
Is tube light capacitive load?
no
