Parallel Circuit Troubleshooting
In parallel circuits the applied voltage is the same across each parallel branch, and the current in each branch equals the applied voltage divided by the resistance of the branch.

Why does ammeter[A] read negative? Answer Below:

In above circuit the current in each branch is the same because resistors are the same. In the circuit below one resistor changed value.
Observe ammeter reading and determine which resistor failed. Answer Below.

Why does Ammeter [A] read negative?
Answer: Because of orientation of Ammeter. If I connected + side of Ammeter [A] to plus side of the 5VDC source than meter would read positive but the "A" would be upside down.

In lower animation, which resistor failed?
Answer R2 resistance increased.

JavaScript for scientific Calculation You may have noticed that I have not discussed calculations in this tutorial. I teach calculations using JavaScript. JavaScript programs can be developed with Notepad and Internet Explorer. These programs are on most computers that use Windows.

These animations are great for those who have an electronics book and want to test their skills, but what about viewers without an electronics book. Don't fret, download our free eBook: Electronic Concepts . Just a click away.
