Equations from Circuit Diagrams In this section, we will look at several example circuits and develop the state equations following the procedure outlined in the previous section. The circuit above consists of two batteries with voltages B1 and B2, one capacitor and two resistors.

Here are the steps we follow, all stated in further detail in the previous section: Indicate current arrows, and draw or just imagine implied voltmeters consistant with your current arrows for the elements and consistent with the battery polarity for the batteries.

The current arrow on B1 should be up; the rest are up to you. Write loop rules and node equations. Find the state equation s. Below, we will solve the problem in this way. But note the following: You could have replaced R2 and R3 by a single equivalent resistor of resistance RS.

To do so, first write the value of that resisitor in terms of R2 and R3. Having done the above replacement, redraw the circuit. Now, you can replace RS and R1 by a single equivalent resistor of resistance Rp.

To do so, write the value of Rp in terms of R1 and RS. For practice, you might want to find the state equation as requested above by using your simplified equivalent circuit. If you do so, you should obtain the same answer that we do below.

OK, here is the solution for this problem, step by step: First, we draw in the current arrows.

Note that I have only drawn one arrow next to b1, and have not drawn separate currents for C1 and b2: I am implicitly noting that these elements are simply in series and will have the same current. I have also drawn in three nodes. Since I have already noted that b1, b2 and C1 are simply in series and have the same current, I have not drawn nodes in between these elements.

If you want to draw in those nodes, that is fine -- the node equations you write down will then tell you the currents in each of these elements is the same!

Finally, I have drawn in plus and minus signs across my elements and batteries - these are consistent with our rules for voltmeters in circuits and I will use these signs when I apply KVL.Teacher guide Matching Situations, Graphs and Linear Equations T-3 task questions correctly, use the Rescue Helicopter task plombier-nemours.com and Selling Candles is a more structured task than Rescue Helicopter, so makes less demand on students’ problem solving skills.
