The main operation of a relay comes in places where only a low-power signal can be used to control a circuit. It is also used in places where only one signal can be used to control a lot of circuits. The application of relays started during the invention of telephones. They played an ...
To check the relay on the circuit board, attach one lead to the connection after the relay that leads to the blower motor and the other to a ground. With the thermostat on, this should have the same reading as the above test. This will determine if the power is making it past the re...

Is relay a protection device? Protective relay work as asensing device, it senses the fault, then known its position and finally, it gives the tripping command to the circuit breaker. ... The relay must come into action whenever there is a fault and must not operate if there is no fault...
When working on a circuit board, it may be necessary to lift one of the leads of the resistor from the board to measure the correct resistance of the resistor. The resistance measurement displayed by a digital multimeter is the total resistance through all possible paths between the test lead...
Thermal cycling, the repeated oscillation between temperatures over the lifetime of an electronic device, can cause failure. Learn how to avoid it in your designs.
