The user has to drag and drop the desired components on the virtual breadboard and then wire them with the help of click-to-connect option. One can also analyze different parameters and then change the layout.


There are three editions of the tool named as Hobbyist, Hacker and Geek, whereby only the first one is available free of cost. However, it’s restricted to the use of 10 components per circuit, 50 simulations per month and 5 circuits saved in the cloud. Moving on the Hacker edition (worth $2.99/month) opens up unlimited components along with 250 simulations per month and 50 circuits saved in the cloud. Lastly, the Geek (worth $3.99/month) can be availed with an unlimited access of every element.

5. DC/AC Virtual Lab

DC/AC Virtual Lab

This circuit simulator claims to present a realistic interface for the students and hobbyists who love experimenting with electric circuits. The users can conveniently design DC/AC circuits along with components like wires, batteries, resistors and then compute the voltage, resistance, etc. It can also be utilised for instructing the students in an interactive manner about using the circuit breaker, testing the capacitor, or locating a short circuit.

It involves the realistic behavior of devices and components such as current flow, burnout and lighting. Besides, users can easily build, simulate and measure their circuits using flexible wires and finally there is an option to view share as well as tweet the created circuits. DC/AC Virtual Lab is a tool with simple user interface and a fast simulation engine.


The trial version is completely free while the student, hobbyist, and classroom versions cost $42, $84 and $234 on an annual basis. For all these aforementioned editions, the user has to sign up on the website.
