-- Two loads ... each of which dissipates 210 watts on a 120V supply ...

when wired in parallel, dissipate 420 watts.

-- Two others in series also want to dissipate 420 watts, so each of those

dissipates 210 watts on a 60V supply.

Power dissipated is proportional to the square of the voltage, so on a 120V supply,

each of these would dissipate 840 watts .

Q: What wattage of heaters would you use if 2 are wired in series with 120 vac to equal same as 2 heaters of 210 wattage each wired in parallel?

Write your answer...

The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.

No,a parallel will win because it has more power and had equal number of energy!AnswerNeither will 'win'. Each has advantages/disadvantages compared with the other -it depends upon their application. Parallel circuits don't necessarily 'have more power' and an 'equal number of energy' (sic).

Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.

1.In series connection the total resistance is equal the total number of resistor that was connected in series 2.the current is constant in a series connection 3.in a series connection total voltage is equal the number of of volt per cells

4ohms in series,2ohms in parallel.

No it will impose the voltage of the three series batteries across the terminals of the paralleled battery. Batteries can only be parallel when all of the voltage potentials are near equal.

In a series circuit the current flow in each element is equal but voltage across the each element is differ. In a parallel circuit the voltage across the each element is equal but current flow in each element is differ.

The batteries can be connected in parallel or in series. In parallel, good batteries of the same voltage will have a total voltage across them equal to the voltage across one of them. Those batteries in series will have a total voltage equal to the sum of the voltage of each of the batteries.

In series resonance, the inductance and the capacitance are connected in series, but in parallel resonance they are connected in parallel. In series resonance, at an input signal with a frequency equal to resonance frequency, the total impedance of both inductive and capacitive elements together is zero (or they appear as short circuits) unlike the parallel resonance case in which it is infinite and they appear as an open circuit.

A quadrilateral has four sides that may or may not be equal or parallel If two sides are parallel and the other sides equal but not parallel it is a trapezoid

It is not possible to have a quadrilateral with four parallel sides - this would bea series of four parallel lines that do not intersect.A quadrilateral with four sides of equal length is a rhombus, however.And a quadrilateral with 2 pairs of parallel sides is a parallelogram.

You can't. Two 4 ohm speakers in parallel equal 2 ohms, and two in series equal 8 ohms. It is possible to wire four 4 ohm speakers so that the load is 4 ohms though. Put two in series (8 ohms). put the other two in series (8 ohms). Then put the two sets in parallel (two 8 ohm sets in parallel equal 4 ohms).

In series circuit we have the same current through out the circuit. But in parallel circuit we have different current in different limbs which have been connected in parallel In series circuit we have to add the different potential differences to get the total potential difference. Hence V = V1 + V2 + V3 + ------ But in parallel circuit the total current entering into the parallel network will be equal to the sum of currents in individual limb. So I = I1 + I2 + I3 + -------

Kirchoff's Current Law states that the signed sum of the currents entering a node is equal to zero. In a simple parallel circuit, say with one battery and two light bulbs, this means the current coming out of the battery will be exactly equal to the sum of the currents entering the two light bulbs. In a series circuit, it also means that the current at every point in the circuit is the same. A parallel circuit can be construed as a special case of a series circuit, when you start to combine elements. Kirchoff's Voltage Law states that the signed sum of the voltage drops around a series circuit is equal to zero. Since a parallel circuit can be construed as a special case of a series circuit, this means that voltage across parallel nodes is equal.

It can do. The non-parallel sides of an isosceles trapezium will be equal. Also, one of the non-parallel sides could be equal to one of the parallel sides.

Kirchoff's voltage law: In a series circuit, the signed sum of the voltage drops around the circuit add up to zero. Since a parallel circuit (just the two components of the parallel circuit) also represents a series circuit, this means that the voltage across two elements in parallel must be the same.Kirchoff's current law: The signed sum of the currents entering a node is zero. In a series circuit, this means that the current at every point in that circuit is equal. In a parallel circuit, the currents entering that portion of the circuit divide, but the sum of those divided currents is equal to the current supplying them.

voltmeter internal resistance is very high , nearly equal to open circuit

In series circuits, the resistance adds up. In parallel circuits the resistance is reduced by the formula R1 X R2 / R1+R2. So two 4 ohm resistors in parallel would be equal to (1) 2 ohm resistor in place of the (2) 4 ohm resistors.

Any regular polygons with an even number of sides can have opposite sides equal and parallel.For quadrilaterals, if any two sides are equal and parallel, the other two sides must also be equal and parallel, and it is a parallelogram (square or rhombus). If the equal sides are not parallel, the figure is a trapezoid (UK trapezium).

If the overall load consists of:'R' = resistance of each individual resistor'S' = number of resistors in each series row'P' = number of series rows connected in parallel,then the effective overall DC resistance of the entire network is[ R S / P ]

An isosceles triangle. It has two pairs of equal sides, which are also not parallel.

Because if they were parallel but not equal, the other two sides would not be parallel.

A kite has two pairs of equal sides with no parallel sides.

The current through each resistor is equal to the voltage across it divided by its resistance ... exactly the same as in a series circuit.
