A 6.4 µF capacitor is used to store electrical charge and regulate the flow of current in a circuit. It acts as a temporary energy storage unit that can release its stored charge when needed.
The 47.0 V EMF (electromotive force) source provides a potential difference that pushes electrons towards the capacitor, causing it to accumulate a charge. The higher the EMF, the more charge the capacitor can hold.
When the EMF source is disconnected, the capacitor will maintain its charge. This is because the capacitor acts as an insulator and prevents the flow of electrons, keeping the charge in place.
Yes, the charge on a 6.4 µF capacitor can be increased by either increasing the EMF source or by connecting multiple capacitors in series or parallel. This will increase the total capacitance and therefore, the amount of charge that can be stored.
The charge on a capacitor can be calculated using the formula Q = CV, where Q is the charge in coulombs, C is the capacitance in farads, and V is the voltage in volts. In this case, the charge on the 6.4 µF capacitor can be calculated by multiplying its capacitance (6.4 µF = 6.4 x 10^-6 F) with the voltage of the EMF source (47.0 V).
