Physics numerical four capacitors each of 2micro farad are connected in such a way that the total capacitance is also 2 micro farad show what combination gives this value?
In order to connect four 2 microfarad capacitors such that the total capacitance is still 2 microfarads, connect two pairs of capacitors in series, and then connect the pairs in parallel. It does not matter, since all four capacitors are equal in value, if the center point is connected together or not.
Why capacitor connected in parallel in circuit?
Any answer "why" will depend on the rest of the circuit, which may an electric motor, a filter, or any number of other applications.If you're asking about 2 or capacitors in parallel, it is to provide a higher capacitance, since the total C will be the sum of each device's individual capacitances.Ctotal = C1 + C2 + C3 ...+ CnConversely capacitors in series obey the reciprocal law:1/Ctotal = 1/C1 + 1/C2 + 1/C3 ...+ 1/Cn
What is the resistance between any two of the corners if Three 3 ohm resistors are connected such that it make triangle.?
2 ohms. It is like connecting two 3 ohm resistors in series and then these two series resistors are connected in parallel with third 3 ohm resistor in parallel
When two capacitors connected with resistance in series?
(r+(c/2))
How do you connect your two 250w solar panels in a 24v system?
The best would be parallel as these panels normally have > 30V output voltage, which would be sufficient for a 24V inverter/load.There is also a risk of overvoltage on your charge controller connecting them in series, check if your charge contrroller can accommodate the sum of the max output voltage of the 2 panels before attemptins series on this configuration.There are additional efficiency advantages of connecting your panels parallel.
Two capacitors of 2µF are connected in parallel A 1 µF capacitor is added in series What is the combined capacitance?
For capacitors connected in parallel the total capacitance is the sum of all the individual capacitances. The total capacitance of the circuit may by calculated using the formula: where all capacitances are in the same units.
How do you calculate total energy for a circuit that has three capacitors(10µF 15µF and 30µf) and a 20v dc supply?
Energy = (Capacitance*(Voltage)^2)/2. Three capacitors are there. Are they in series or in parallel. It is not mentioned. So friend has given only the formula as guidelines.
What is the advantage of using 2 or more capacitors in parallel in circuits instead of one larger capacitor?
When capacitors are connected in parallel, you add up their capacitances to obtain the overall capacitance of that 'bank'. The main reason for using two capacitors in parallel when decoupling, is that they have a lower overall inductance (electrical resistance in essence) to one large capacitor, which improves the decoupling effect. Using two capacitors also provides better high-frequency filtering for the power bus. One minor advantage of this, is that, you can obtain a certain redundancy when using two smaller capacitors in parallel, instead of only one, as if one capacitor fails, the other still acts to decouple the circuit, to a certain extent.

Formula to find the median of a trapezoid?
To find the median of a trapezoid, you would add the lengths of the two bases of the trapezoid and then divide by 2. This will give you the median, which is the segment connecting the midpoints of the two non-parallel sides of the trapezoid.
How do you find voltage across capacitors in a serial parallel circuit?
Voltage across all parallel capacitor's is same i.e. it is equal to supply voltage, it can be measured using digital volt meter (any high input impedance volt meter). When capacitors are in series; voltage drop depends on charge stored in the capacitor. it can be given by the formula V x V = 2 / (joules x capacitance). This voltage can also be measured using digital volt meter.
How capacitor is denoted?
2 parallel lines. sometimes one line is curved, if so that is the outside or "shield" foil.. ANSWER : A curved parallel line define a less positive terminals of the two lines. capacitors do not have shields

What is the slope of a line that is parallel to y equals 2?
The line y=2, and all lines parallel to the x axis, have a slope of 0. The formula for this line in particular can be expressed as y=0x +2.
What is the formula for finding trapezoid?
Area of a trapezoid = 0.5*(sum of parallel sides)*height
