When an electric current flows in an external magnetic field, it experiences a magnetic force, as in electric motors. The heat loss, or energy dissipated, by electric current in a conductor is proportional to the square of the current. A common unit of electric current is the ampere, which...
(General Physics) the strength or intensity of an electric field at any point, usually measured in volts per metre. Symbol:E Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 1994, 1998, 2000, 2003, 2006, 2007, 2009, 2011, 2014 ...
(General Physics) physics the electric flux density when an electric field exists in free space into which a dielectric is introduced. Symbol: D Also called: electric flux density Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 1994, 199...
The electric flux through an surface is then defined as the surface integral of the scalar product of the electric field, and the area vector and is represented by the symbol Φ. It is a scalar quantity and has an SI unit of newton-meters squared per coulomb (N·m2/C). In general, ...
What is the magnitude of the electric field? The magnitude of the electric field is a measure of the strength of the electric field at a specific point. It is represented by the symbol E and is measured in units of Newtons per Coulomb (N/C)....
Adapted from www.physicscentral.com. Now let us look at what happens when a dipole interacts with an electric field. When a dipole is placed in the electric field it experiences a torque that causes it to rotate. This is illustrated in Fig. 6.13. The positive pole pulls it one way and...
b, Dependence of the amplitude of the two main spectral peaks on the terahertz electric field. The standard error is smaller than the symbol size. Blue solid lines are quadratic fits to the data at ω− and ω+. Yellow lines indicate the field dependence of the ω− and ω+ peaks ...
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...
In the current study, droplets dynamics under an asymmetric electric field in a T-junction are numerically studied using COMSOL Multi-physics software. The effect of different factors such as dimensionless length of mother droplet (L*), Capillary number (Ca), and electric capillary number (Cae) ...
a gravitational field. It is as if the charge is going down an electrical hill where its electric potential energy is converted to kinetic energy. Let us explore the work done on a chargeqby the electric field in this process, so that we may develop a definition of electric potential ...
