I've attached jpegs that show the circuits that I'm working with. My problem is that I don't know how to find the values of Ct and Rt for a specific firing angle. What formulas are needed? Is the calculation affected by the fact that there are two different loads (see circuits 1 and 2 jpegs)? What process must I go through to fi

Use nodal analysis to determine the node voltages and also the branch currents of the circuit as shown in Fig.3.2. Use Matlab to calculate these values. Enter these readings in Table 2 under the 'calculated' column. (Note: Node voltage VA is known, that is, 10 V. So you need to write nodal equations at B and C only for the circu
