What are three examples of electric fields?
Light, X- rays, radio waves, microwaves etc. contains electric field component’s in it. There is an external electric field in a current carrying conductor. Electric fields are generated by charges and charge configurations such as capacitors.
What are the 2 sources of electric fields?
The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field.
Where are electric fields used?
The electric field lines flow from positive to negative charges. Such sources are well suited for surface applications such as wound healing, corneal repair or even brain and spinal stimulation with closely-separated, inserted electrodes.
Can electric field be negative?
Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
What are sources of electric fields?
They are generated by natural phenomena like the Earth’s magnetic field but also by human activities, mainly through the use of electricity. Mobile phones, power lines and computer screens are examples of equipment that generates electromagnetic fields.
