Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...
The circuit was designed to provide a voltage over and under the specified value with the use of a switch that will be operated by a relay. LM741 – a general purpose single operational amplifier with ...
The essence of the circuit is for the input of tone and signal to provide an activation for the relay switch. Relay – an electrically operated switch where the current flowing through the coil of the ...
