The electric force and electric fields are closely related. Electric fields are created by charged particles and are responsible for exerting a force on other charged particles within the field. The direction of the electric force on a charged particle is determined by the direction of the electr...
Those equations state that: (1) an electric field is generated by the electric charges; (2) a flowing current or alternating electric field can generate the magnetic field; (3) the magnetic field has no source; (4) an alternating magnetic field can create an electric field through induction...
Let's assume that we have a hollow sphere with holes at opposite ends of the diameter. What would be the field inside the hollow sphere? I know that we can look at this as the superposition of the hollow sphere without holes and 2 patches with opposite surface charge density. For some ...
To solve the problem, we will use the formulas for electric field (E) and electric potential (V) due to a point charge (Q) at a distance (r) from the charge. Step 1: Write down the formulas for electric field and potential.The electric field (E) due to a point charge is given ...
Let’s try to understand the difference between the two. The particles that carry electric charge through conductors are mobile or free electrons. The direction of an electric field within a circuit is, by definition, the law that positive test charges are pushed. Thus, these negative charge ...

Beside conventional position (optional) and speed controllers, the motor control task is also decomposed into two sub-tasks which are armature current and field controls, in association with two main aforementioned components of the motor. In the control layer in Fig. 2, the superscript “∗”...
When the dipole is parallel to the field, the torque on a dipole is minimum. Q5 Give an example of the electric dipole. A pair of electric charges of two opposite signs and equal magnitude separated by a distance. Stay tuned with BYJU’S to learn more Physics concepts with the help of...
the electric charge is defined as the basic physical property of matter that causes it to experience a force when kept in an electric or magnetic field. q2 how is the electric charge classified? electric charges are classified as positive charges and negative charges. q3 what are positive ...
Additional charge that a liquid carries is distributed inside the liquid with some preference for the liquid-air interface. Consequently, the interface for both macroscopically neutral and charged liquids is technically charged at the atomic level. Their exposure to an external electric field can ...
