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 transistor is a crystal of n-type confined between two crystals of p-type or a crystal of p-type confined between two crystals of n-type, There are two types of connection for a transistor in...
Oscillating circuit Oscillating circuit is the electric circuit in which there are the interchange of the energy stored in the induction coil as a magnetic field and the capacitor as an electric field, The...
Impedance In an electric circuit containing an AC power supply together with inductive coils, capacitors & resistors, the AC current would be opposed by reactance (inductive reactance or capacitive reactance) in addition to the...
The transformer is a device used to step up or to step down an AC voltage, It is used in some home appliances such as bells and fridges, It is used to decrease the...
Analog measuring instruments depend on the torque that is generated in a moving coil carrying current in a magnetic field, They depend on pointer to give the value of the quantity, such as moving...
