If the radioactivity is induced in an element by irradiation with, for example, neutrons, the process is known as artificial […]

There are two types of radioactivity – natural and artificial radioactivity. The phenomenon of radioactivity was first discovered by Henri […]

In 1913 Niels Henrik Bohr published his new theory of the atoms constitution. Just like Rutherford he assumed that electrons rotate around the nucleus. […]

Modern atomic theory provides a reasonably satisfactory explanation of the properties of matter, the mechanisms of chemical change and the […]

When capacitors are connected across a direct current DC supply voltage they become charged to the value of the applied […]

A.C. circuits are circuits through which an alternating current flows. Such circuits are used extensively in power transmission, radio, telecommunication […]

Up to this point inductance and capacitance have been explained individually in ac circuits. The rest of this part will […]

So far you have been dealing with the capacitor as a device which passes ac and in which the only […]

The current, I, in an RLC series circuit is given by I = V/Z = V/√R2 + (XL – XC)2 Where XL = […]

Power in an A.C. Circuit The average power in an a.c. circuit is given by P = IVcosɸ where I, […]
