Why is a transformer not classified as an electric machine?
Transformers do not actually make conversion between mechanical and electrical energy, but they transfer electric power from one circuit to another circuit. … Whereas, step-down transformer decrease the voltage level with the corresponding increase in the current so as to keep the power constant.
Is a transformer A device an apparatus or an equipment?
A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. … A transformer has no moving parts and is a completely static solid state device, which insures, under normal operating conditions, a long and trouble-free life.
What are the two main types of transformers?
There are two types of potential transformers; the conventional wound type (or electromagnetic type) and the capacitor voltage (potential) transformer. For voltages exceeding 100 kV (phase) the conventional type of potential transformer becomes extremely expensive owing to the insulation requirements.
Do all machines work on electricity?
Answer: Yes all the machine work on electricity।
What is meant by DC machine?
A DC Machine is an electro-mechanical energy conversion device. There are two types of DC machines; one is DC generator, and another one is known as DC motor. A DC generator converts mechanical power (ωT) into DC electrical power (EI), whereas, a DC motor converts d.c electrical power into mechanical power.
