The speed and current during the final stages of the lightning stepped leader were determined from features of the electric field waveform. The average speed of the leader tip was found below the height where dE/dt was zero for close lightning. This height was in the range 0.62.0 km for ...
an electric current may pass through the air between two charged bodies, and is observed as a visible spark; when the spark passes from a human body to another object it may be felt as a mild to strong painful sensation. Electricity in the form of electric current is put to many practica...
Electric current definition Electrical current is the flow rate ofelectric chargein electric field, usually in electrical circuit. Using water pipe analogy, we can visualize the electrical current as water current that flows in a pipe. The electrical current is measured in ampere (amp) unit. ...
This work discusses the processes involved in different modes of charge transfer in negative lightning flashes, taking as reference video-records obtained with a fast camera and records of current and close electric-field measured at Morro do Cachimbo Station. The data of two downward and one upwar...

We used T1w structural MRI from 32 healthy volunteer subjects and modeled the electric field distribution for a fronto-temporal tDCS montage. For five different computational modeling pipelines, we quantitatively compared brain tissue segmentation and electric field predicted in whole-brain, brain tissues...
In conclusion, we performed nonlinear dynamical analysis of decompositions arising from electronic instabilities such as current-controlled NDR and Mott-transition instabilities, and showed that both current-density and electric-field decompositions are possible depending on the operating conditions and the ty...
The electric current is due to the flow of electrons, whereas static electricity is due to the negative charges from one object to another. The electric current generates only in the conductor, whereas static electricity generates both in the conductor or insulator. How Does an Electric Current ...
However, for the twin-lifted flame to exist, the flow field upstream from the lifted flame edge should be influenced by electric field. In this regard, we have systematically investigated cold flow to isolate the Conclusions Motivated by an observation of twin-lifted flames in free jets by ...
2. In order to see the current flowing, you need to use Electric Currents interface in ACDC module. You can give DC voltage as choosing an electric potential (or a terminal). You should also choose a boundary for ground. After the simulation, you can see the electric field in study grou...
