Question

True or False (No explanation needed)

Capacitor is a circuit element and can store electric charge. A capacitor consists of two or three conductors. Capacitance is a capacity. Just like the capacity of a milk-bottle is the volume of milk it can store. The capacitance of a capacitor is the amount of maximum charge the capacitor can store. Capacitance is a capacity. The amount of charge stored in a capacitor is proportional to the voltage difference between the two conductors of the capacitor. The capacitance is the amount of charge the capacitor can store per unit of voltage difference. When there are two capacitors, the one with more charges stored has a higher capacitance. When there are two capacitors, if they have the same potential difference, the one with more charges stored has a higher capacitance. When there are two capacitors, the one with less potential difference has a higher capacitance. When there are two capacitors which stored the same amount of charges, the one with less potential difference has a higher capacitance. You can increase the capacitance of a capacitor by adding more charges on it. You cannot increase the capacitance of a capacitor by adding more charges on it. Because when it stores more charges, the potential difference (voltage difference) between the two conductors also increases, the ratio between Q and Delta V will not change. You cannot increase the capacitance of a capacitor by adding more charges on it, because the capacitance of a conductor is determined by its shape and the separation between the two conductors. Consider the definition equation of capacitance: C = Q/Delta V, its SI unit_____is equal to_____(relating it to to Coulomb and Volt) Typical capacitors have a capacitance ranging from pF to mu F, which means when it is connected to a battery of 1 Volt, it will only store a "small" amount of charge ranging from 10^-12 C to 10^-6 C. When an uncharged capacitor is connected to a battery (that means each plate is connected to one terminal of the battery), charges start to flow to "charge" the capacitor, until the voltage difference between the two plates arc equal to the potential difference between the battery's terminals. The two plates will have the same amount of charges with opposite sign.
