Is that what you are asked?Kelsi_Jade said:If so, how do I go about finding the total current?
You are given two values for the current at different times. You'll want to use them at some point...Kelsi_Jade said:Here is what I have so far. Am I going the right direction?
If so, how do I go about finding the total current?
Yes, so you have a basic RC circuit (resistor - capacitor circuit).Kelsi_Jade said:Well, since the resistors are in series you can combine them to equal one resistor with a resistance of 3+1= 4kOhm.
The capacitors in parallel would equate to one capacitor with 3+C= (3+C)microFerrads.
Current with respect to time would be = Q/Δt ?
The drop in current after 14ms indicates that the capacitor has reached its fully charged state. This is due to the fact that the capacitor's voltage has increased to match the voltage of the power supply, resulting in a decrease in current flow.
Capacitance at C can be calculated using the formula C = Q/V, where Q is the charge stored on the capacitor and V is the voltage across the capacitor. In this case, the charge and voltage can be measured at the 14ms mark to determine the capacitance at C.
The capacitance at C is primarily affected by the distance between the capacitor's plates, the surface area of the plates, and the type of material used as the dielectric between the plates. Additionally, the amount of charge and voltage applied can also impact the capacitance.
The capacitance at C is constant as long as the physical properties and conditions of the capacitor remain unchanged. However, if there is a change in any of these factors, the capacitance may also change. For example, if the distance between the plates is altered, the capacitance will also be affected.
The capacitance at C can be increased by increasing the surface area of the capacitor's plates, decreasing the distance between the plates, or using a material with a higher dielectric constant. This allows for more charge to be stored on the plates, resulting in a higher capacitance value.
