The electrons still rotate around the nucleus due to the attraction force between the protons in the nucleus and electrons. The electrons may leave the atom and move freely due to the weakness of...
The electric capacitor is made up of two parallel metal plates separated by an insulator and stores the electric energy in the form of an electric field, The capacitive reactance does not cause energy...
Analog measuring instruments depend on the torque that is generated in a moving coil carrying current in a magnetic field, They depend on a pointer to give the value of the quantity, such as...
Some electric circuits consist of many branches and are too complicated to be managed by Ohm’s law because the electric current passing through them is different in each branch, For such cases, a German...
