LCR Circuit

LCR Circuit

LCR Circuit We know that there are two types of connection series and parallel. Series circuit is one in which current remains the same along each element. Now we will talk about LCR circuit. The LCR circuit analysis can be understood better in terms of phasors. A phasor is a rotating quantity. For an inductor (L), Read more about LCR Circuit[…]

Resistivity of Metals

Temperature dependence of Resistance

Temperature dependence of Resistance Resistance is fundamentally the ability of the material to restrict the passage of electric current. Thus, just as material properties such as density, size, magnetization etc. change with temperature, so doe’s resistance. Resistance is really a bulk property; the resistivity on the other hand is a material property. Resistivity of Metals: The resistivity Read more about Temperature dependence of Resistance[…]

Voltage Divider

Voltage and Current Dividers

Voltage and Current Dividers Voltage Divider: A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics. It is interesting and useful to consider Read more about Voltage and Current Dividers[…]

Parallel Capacitances

Series and Parallel Capacitors

Series and Parallel Capacitors When capacitors are connected in series the total capacitance is less than any one of the series capacitors’ individual capacitance. If two or more capacitors are connected in series the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacing’s of the individual capacitors.
