Draw a copy of the circuit diagram in your lab book. Use arrows to show the direction in which the current flows through the circuit. Label the input circuit and the output circuit of the ...

Shini explores electric current, voltaic cells, and how we get electric charge.

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

To learn more about why current flows through the path of least inductance, you can download Joffe’s presentation (PDF format). The presentation also discusses how return paths affect circuit ...

Current passing through the inductor establishes a magnetic flux. The resulting magnetic field can store energy that is transferred back and forth between the electric circuit and the magnetic circuit ...

Current is measured using an ammeter. To measure the current flowing through a component in a circuit, an ammeter is always connected in series with the component.

In order to test and characterize optical front end circuits, a controllable, high bandwidth, microamp-level current source is needed. However, most optocouplers on the market have large CTR variation ...

Many introductory books on electricity try to relate voltage to water pressure, electric current to water flow, and resistance to changes in pipe volume.

ORNL researchers are designing and increasing the capacity of a new type of semiconductor-based circuit breaker, which can ...
