Dielectric materials Dielectric materials are essentially insulators, which means that no current will flow through the material when a voltage is applied. However, certain changes do happen at the atomic…

Impedance and reactance An element in a DC circuit can be described using only its resistance. The resistance of a capacitor in a DC circuit is regarded as an open…

What is inductance? Electric inductance is a property of all conductors. A change in the current flowing through the conductor creates (induces) a voltage in that conductor, as well as…

What is capacitance? Electric capacitance is the ability of a conducting body to accumulate charge. The capacitance value of a capacitor is obtained by using the formula: where C is…

What is electric charge? Electric charge is a fundamental physical property of matter. Electric charge can be positive or negative. Matter repels other matter of the same charge and attracts…

What is an electric field? An electric field is a special state that exists in the space surrounding an electrically charged particle. This special state affects all charged particles placed…

What are ceramic capacitors? A ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the producion of capacitors, as…
