The document summarizes the construction of a time delay circuit. It describes obtaining components like a PCB, transistor, capacitor, diode and time delay relay. The circuit was then constructed by soldering the components together according to a diagram. Testing showed that the circuit worked as intended when powered with 12V. The time delay can be adjusted by changing the 470k resistor value, with lower resistor values producing shorter delays.

- 1. Project Report (Time Delay Circuit) First of all i slect the time relay then i make a proposal of this circuit . then i go to the electronics shop and bought pcb, transister,capacitor,diode and time delay relay and other electric equipments of the related circuit. then we bring equipment of circuit in elctric shop in university. then we made a circuit acccording to the diagram and connected the components with other components with the help of soldering iron and soldering wire . then i connected transister on PCB with help of soldering . after connecting transister i connected resister and capasitor to the circuit with
- 2. the help of soldering . then in the end connected diode and time delay relay with the help of soldering . After all implemention of related equipments and other things and recheck the circuit for working . i gave it 12 v to circuit and circuit is working . i note all the the measure the reading of this circuit . USES: This circuit is used for double instructions, time delay and time limit . CHARACTISTICS : We change it time delay constant against the changing of using 470 k resistor . if we change in low value then time constant is low and then we change in high value the delay time constant will be high ./ Components Quantity Price c945 Transister 2 35
