Week -2

1. Doorbell model:

OBJECTIVE:

here using solenoid we oparate the doorbell.Using PS switch we on and off the circuit and oparate the solenoid.Also we use a force sensor for display the door bell physical responce.

where we use a voltage source as 50 V and a solinoid which actually oparate at 50 volte.Here we found from the result that the doorbell respone same time with input signal.

This is out put responce.

2. problem:

Objective:

using thermistor and controlled temperature source to control the motor as require conditions.

the motor will on whenthe tempareture is greater than 298 k or 25 c tempareture.

in this circuit we use switch thrisold voltage 298k or 25c for switching.

for thermistor opatation voltage 10 V.

and a 10 V DC motor

in and output responce:

input signal parameters:
