The relay is simply an electrically operated switch i.e. relay has two states and state of the relay depends upon the presence of electrical signal. The relay is usually cuboid shaped and has 5 pins. WHERE TO USE: The relay is used as a switch between two independent circuits. I.e. one circuit can be used […]

Q: Selection of Power Supply
REQUIREMENTS: Suppose I have the requirement of a power source with very high current rating of 5A and 6V but lighter in weight. Also we can’t have a supply of 220 V to the system. SELECTION: As we can’t have a 220V, hence we can’t design the power supply our self by transforming AC to […]
DC power supply from AC source
A power supply converting AC line voltage to DC power must perform the following functions at high efficiency and at low cost. The advantage of this kind of power supply over batteries is that this power supply is low cost and also long lasting. We have to perform the following functions to convert AC power […]
Power Supply – Introduction
The power supply is a critical component for any system. No motor or IC would run without power supply. There are various options which can be considered while looking for a power supply. Designing specific DC power supply from AC source Battery power
