We can calculate the voltage dropped across the resistor R 2 using this equation:įrom the equation above, you can solve the voltage drop across R 2:
Since the current is common to both resistors, the current across them are equal.
In a voltage divider, the output voltage always scales down the input voltage and the current flowing through the series network that can be calculated using Ohm’s Law, I = V/R. Using the two equations above, it will give you: Voltage Divider Equations Having the supply voltage, we can apply the Kirchoff’s Voltage Law and Ohm’s Law to find the voltage dropped across each resistor derived in terms of the common current flowing through them. Thus providing an IxR voltage drop across each resistive element. It follows that the same value of electric current that flows through each resistive element of the circuit has nowhere else to go. The input voltage is applied across the series resistances R 1 and R 2 and the output is the voltage across R 2. The voltage divider referenced to ground is created by connecting two resistors in series. The voltage drop across R2 is the output voltage and that’s also the divided voltage across the circuit. Overall, Solve Elec worked well for me.Voltage Divider Circuit Voltage Drop and Input Voltage In case you place a wrong component then in order to delete that component you have to select the cut option and cut the component from the circuit. All the options work flawlessly for me, however, I missed the undo option. Solve Elec is very helpful in order to test electrical circuits and it is good for learning about the working and solving electrical circuits.
You might want to try similar software CircuitMod. The help file has explanation for each and every feature which I really liked.
In order to design your circuit first you have to select AC or DC source of current and voltage. Note that the AC analysis does not work for DC voltage circuits. The user interface gives you the option to draw the circuit for DC/ AC voltage and current sources. Solve Elec is very simple to use and is meant for anyone who wants to learn the basics of electrical circuits. Working With Solve Elec To Test Electrical Circuits: With Solve Elec I was able to view the results on graph and circuit solution for DC and AC voltage sources very easily as shown below (for AC source).
I have used Solve Elec to test electrical circuits in Windows 7 in this article. Also, you can view the graphs plot for different nodes of the circuit which I really like.Īlong with all that Solve Elec offers the option to view Oscilloscope, Transfer function, and Frequency response for AC analysis of the circuit. This feature is really helpful when you are learning about working of an electrical circuit. Why I like Solve Elec is because you can design the electrical circuit and view the solution of the circuit and see how the solution is carried out. Solve Elec lets you design the electrical circuit using the basic electrical components like resistors, capacitors, inductors, and some semiconductor components that include diodes and amplifiers and view the result for the circuit. Solve Elec is free software to test electrical circuits.
