3 Phase power factor correction

Hi, I'm doing an assignment on 3 phase power factor correction on electric motors (Lagging). One question asks me to comment on the difference between pf correction capacitors connected in star and delta. Could you give me any ideas please?

The Tevenin and Norton equivalent circuit

Hi How can I find the Tevenin and Norton equivalent circuit for the attached circuit? Please write the steps. Thanks

Systems Approach

*10. For the network of Fig. 10.53: (a) Determine AVNL, Zi and Zo. (b) Sketch the two-port model with the values determined in part (a). (c) Determine Av and Avs. (d) Change Rs to 1k and determine Av and Avs. What is the effect of increasing levels of Rs on the voltage gain? (e) Change Rs to 1k and determine Avnl, Zi, and Zo. What is the effect of increasing levels of Rs on the parameters? (f) Change RL to 5.6k and determine Av and Avs. What is the effect of increasing levels of RL on the voltage gains? Maintain Rs and its original level of 0.6k.

BJT Analysis

For the network of Fig. 8.82, determine RE and RB if Av = -10 and re = 3.8ohms. Assume that Zb = Bre Note: B = 120 ro = 80k ohm (See attached file for full problem description)
