STUDY OF OPERATION AMPLIFIER To demonstrate the function of operational amplifier using TL081 and L272 with discrete components different value of resistors, capacitor. Input can be applied from microphone, LDR. Offset null control is also provided. Output can be fed through the power amplifier into a loudspeaker.
Explore the relationship between linear (tangential) and angular velocity with this setup. A DC-driven motor produces various rotational velocity at various distances from the motor. Different radii are drawn on the disk and pegs can be positioned at specific radii. A photogate may be attached as well, so the time of one rotation is easily measured. Students will then make measurements to calculate the angular velocity, which will be constant for a given motor speed independent of position. However, the tangential velocity will vary based on the radius of the circular path. Kit includes a rotational table, ruler and calipers. Required but not included are a 6 V power supply and a photogate system.
