A motor is controlled by a NO start button, a NC stop button, and an overload device. The overload device is normally closed and opens if the motor overheats. Draw the PLC ladder diagram for the circuit. Include a light that comes on when the motor overheats.
And the information just given to evaluate the potential difference between the plates in terms of Q, R, and d.
Determine the value of the output voltage due to the voltage source only (V01) and due to the current source only (V02).
Calculate: i. The A, B, C, D constants of the line. ii. The characteristic impedance of the line. iii. The sending-end voltage iv. The sending-end current. v. The sending-end power factor. vi. The sending-end power. vii. The power loss in the line..
Discover the basic concept of electronic rectifiers and build up the basic skill of electronic fault-finding and electronic design. You understand the applications of rectifiers design.
1. What is the power spectral density of Y(t) = X(t) - X(t-T) 2. What is the power spectral density of Z(t) = X'(t) - X(t) 2. What is the power spectral density of W(t) = Y(t) - Z(t)
a)Describe the difference between a relay logic system and a PLC control system. Are there any advantages of PLC control system over relay system. Explain the advantages in details with one example.
a 4-pole, 50 hz induction motor has a full load slip of 5%. each rotor phase has a resistance of 0.3 ohms and a standstill reactance of 1.2 ohms. find the ratio of maximum tirque to full load torque and the speed at which the maximum torque occurs..
A 10kVA, 200/400V 50Hz single-phase transformer gave the following test results. O/C test: 200V, 1.3A, 120W, on l.v. side. S/C test: 22V, 30A, 200W on h.v. side. (a) Calculate the magnetizing current and the component corresponding to core loss at ..
ManchesterEncodingFSM the clock (Clk_H) will need to run at a speed that is twice as fast as the clock that defines the boundaries of the RawSerialIn_H serial data bit cell this will allow the FSM to resolve or discriminate the middle of each raw ..
1) When discussing the generation of electron/ hole pairs by light in semiconductors is it best to use the wave or particle rendition of light energy. 2) In what type of electron transition from valence to conduction band is momentum conserved, dir..
If each packet carries 1000 bitsof data, the distance between the sender and receiver is 5000km,link speed is 1Mbps, and the propagation speed is2x108 m/s. Assume no data or control frame is lostor damaged. Ignore transmission time for ACK.
