Which of the coil of the wattmeter has high resistance?
The voltage (or 'potential') coil has the higher resistance, because it is connected in parallel with the load.
Why shunt resistance is connected in the parallel?
Shunt means parallel only..................
When a battery is connected across a high resistance in parallel with a low resistance more power is dissapited in the low resistance Is this statement true or false?
true
High voltage field windings are connected series or parallel?
high voltage field windings are connected in parallel
What will happen to a buzzer connected to a circuit?
If it is connected in series with a circuit then it might raise the resistance too high and fail the system. Parallel connection is a circuit is probably the best bet you have.
Why would a cell connected to two bulbs that are connected in series last longer than if the same two bulbs are connected in parallel?
This question looks like one that has been asked by a high-school teacher with very little knowledge of electrical science, and who doesn't realise that the resistance of a lamp changes appreciable between when it is cold and when it is hot! (Either that, or he is being devious!)So, as stated, this question is not straightforward, because incandescent lamps that operate at their rated voltage and power have a 'hot' resistance that is around 15 - 20 times their resistance when cold. Lamps in series are not subject to their rated voltage and, so, their resistance will be relatively low in comparison. So, what the question comes down to is whether the combined (high) resistance of lamps in parallel (i.e. half the resistance of one of the lamps) higher or lower than the combined resistance (low) of the same lamps connected in series (twice that of one of the lamps)? You could find this out experimentally, but I'd be inclined to believe that the two lamps connected in parallel are more likely to have the higher resistance and, therefore, the cell supplying them would last longer -in other words, opposite to that in your question!Now, if you simply used two resistors (whose resistance doesn't change appreciably with temperature) then the two connected in series would definitely have a higher resistance (twice) than if they were connected in parallel (half), and they would draw less current and the cell would last longer.
High resistance in parallel connected with galvanometer to form voltmeter?
That won't work. To convert an ammeter (a galvanometer is a very sensitive type of ammeter) you connect a high value resistor in series with it.
What is bleeder resistor?
They are resistance connected in parallel with high voltage power supply for the purpose of discharging the energy stored in filter capacitance when the equipment is turned off.
For bulbs connected in series the high watt bulb has high resistance?
No, the highest wattage bulb will have the lowest resistance.
Why must voltmeter be connected in parallel with the circuit component?
Because, by definition, a voltage is the difference in potential between two different points. So the voltmeter must be connected across those points in order to measure that voltage -i.e. in parallel with the points.B
How do you connect a voltmeter in parallel circuit?
A voltmeter is used to measure potential difference across two points in an electrical circuit . The voltmeter is connected in parallel across the circuit element (resistance ) so that its inclusion in the circuit has negligible effect on total resistance and current flowing in yhe circuit A voltmeter has high resistance,if connected in series it will increase of circuit and reduce the current in the circuit
What will happened if cells were connected in parallel connection but in opposite polarities?
You would get a high circulating current through both cells, possibly enough to do significant damage to both the cells and to you, depending on the capacity of the cells. Technically, they would actually be connected in series, not parallel!
