Find the unknown resistance if three resistances of 3 , 6 and x are connected in parallel to give an equivalent resistance of 1.6 . Capacitance is the capability of a material object or device to store electric charge.It is measured by the change in charge in response to a difference in electric potential, expressed as the ratio of those quantities.Commonly recognized are two closely related notions of capacitance: self capacitance and mutual capacitance. In power supply circuits, this capacitor can be calculated to ensure the least ripple at the output. The total voltage rating will not change in a parallel combination. Here is a plot of the field when $a=L$. Thus, the formula for total capacitance in a parallel circuit is: CT=C1+C2+Cn. Because a capacitor gives extremely low resistance for high-frequency signals, so these signals will supply through the capacitor. The multiple connections of capacitors act as a single equivalent capacitor with a total capacitance. So, in the above example, CT = 0.6 uF whereas the larges value capacitor in the circuit is 0.3 uF. For high voltage applications, numbers of capacitor units are connected in series and parallel combinations to form a capacitor bank for required voltage and Kilo VAR ratings.
