Find the overall gear ratio of the gear train shown in Figure 5.49. If the motor is rotating at 500 rpm, what is the rotational velocity of the output gear?
1 kW heating element of a 230 V, 50 Hz electric stove is to be controlled by a triac circuit. The gate circuit of the triac uses a 0.2 mF capacitor and a diac with a break over voltage of 50 V. Calculate the adjustable resistance value to provide ..
a. if the input r(t)=5u(t), ie. R(s)=5/s, find the steady-state of C(t), b. Approximately how many seconds are required for the system to reach steady state note you two time constants to consider, and c. Do you expect the transient response to be o..
Supposed that at t=0, we connect an uncharged 10μF capacitor to a charging circuit consisting of a 2500V voltage source in series with a 2MΩ resistance. At t=40s, the capacitor is disconnected from the charging circuit and connected in parallel wi..
A star connected synchronous motor at 187 kVA, 3-V, 2300V, 47A, 50Hz, 187.5 rpm has an effective resistance of 1.5 ohm and a synchronous reactance of 20 ohm per phase. Determine internal power developed by the motor when it is operating at rated c..
A transformer is needed that will cause an actual load resistance of 25Ω to appear as 100Ω to an ac voltage source of 240 V rms. Draw the diagram of the circuit required. What turns ratio is required for the transformer? Find the current taken fro..
Given a simple series circuit similar to that shown in the given image, determine the load voltage if the source voltage is VS= 1200°V, the load current is IL= 10-30°A, and the cable impedance is ZC= 0.5
When no real time processing is needed the system can be noncausal. Consider the case of averaging an input signal x(n) uner real time conditions. suppose you are given two different filters y{n}= 1/n *(symbol of Sum) x(n-k) on top N-1 at bottom k=..
