What advantage might there be in using two identical capacitors in parallel connected in series with another identical parallel pair rather than a single capacitor?
I honestly think thst people should stop searching for assignment answers on the net. study your books and the given texts for reference to the given questions.
What capacitors are polarity sensitive?
While most electrolytic capacitors are the ones that have a polarity noted as minus "-" and "+" as opposed to ceramic or film capacitors, it's important to note that even electrolytic capacitors could also be labelled as "np" for non-polarized or "bp" bi-polarized, which means the same thing, that there is no plus or minus and the current can flow in both directions. Today a good quality electrolytic, most of the time, will be another color to depict this such as green for example, whereas in older circuits they could sometimes look identical but just be missing the little "-" indicator. So, you need to pay attention to this little detail on older boards when replacing a capacitor.
Does batteries connected in parallel increase the current capacity to the circuit?
If each battery is identical, yes.
What is equivalent of 50 voltage ampere rating to wattage?
The short answer: they are identical: 50VA (through a resistive load) = 50WattsThe long answer:Power can be divided into real power and reactive power. Real power is used to do real work. reactive power is stored and released in reactive elements (capacitors and reactors). A purely resistor is hard to get, having absolutely no reactance or capacitance. Because of this, watts defines the amount of real power available to do work; volt-amps defines the maximum current drawn at a specified voltage.
Should all 3 phases of a motor draw the same amperage?
Yes. they should. The windings in a three phase motor are identical, and provided they are fed with a supply that has the phases at the correct voltage, and at the correct 'phase angles' to each-other, they should each draw the same current from each supply line. (Motor windings are a 'balanced' load - they will all draw the same current from the lines if the supply is okay and the windings are connected correctly, and have no shorts or opens in them.) Some three phase motors can be connected to run off of a single phase line, using capacitors to give phase shifts to simulate 3 phase. This is an 'unbalanced' 3 phase supply as far as the motor is concerned, and while it WILL work, the motor will develop less staring torque, less full load power, and more noise - and it WILL draw different currents in each 'phase' while running.
Can you double the volts by connecting two capacitors?
Two capacitors can be connected in series to double the voltage rating, but they must be identical capacitors and they should each have a resistor in parallel to equalise the voltages, the resistors chosen to pass about 1 mA. With two capacitors in series the overall capacitance is half the capacitance of either capacitor. The combination stores equal charge at double the voltage and the stored energy is doubled.

Are the two sister chromatids that are connected by a centromere identical to one another?
Two sister chromatids that are connected by a centromere are identical to one another. They are duplicate copies of a chromatin.
What is the collection of identical cells that live together in connected group?
Tissue
Three identical resistors each 45 ohms are connected in parallel across a 60-V battery The current through or drawn from the battery is?
If 3 identical 45-ohm resistors are connected in parallel, the net effective resistance of the bunch ...and the load seen by the battery ... is 15 ohms. The current supplied by the battery is60/15 = 4 Amperes.(This assumes that the battery is capable of supplying 4 amps at 60 volts, or 240 watts !)

Why use of capacitors to correct pf?
Power-factor improvement capacitors are connected in parallel with the load, and are rated in reactive volt amperes. If their reactive volt amperes are identical with the reactive volt amperes of the reactive component of the load, then they act to cancel each other, and bring the phase angle to zero (i.e. the load current becomes in phase with the supply voltage). This reduces the value of the load current without affecting the operation of the load, and allows cables and switchgear with lower current ratings to be used than would otherwise be necessary.
Does batteries connected in parallel increase the current capacity to the circuit?
If each battery is identical, yes.
Are sister chromatids identical?
they're identical because they are the product of replication.
What is a collection of identical cells that live together in a connected group?
A collection of cells that function together makes up a tissue. A collection of tissues that function together makes an organ.
What will be the output voltage of two 12v batteries connected in parallel?
When two identical 3v batteries are connected in series with the negative terminal of one of them in contact with the positive terminal of the other the total voltage of the combination is 6v.
