A screwdriver placed across two wires in a circuit creates a circuit?
Depending on where in the circuit the screw driver is placed it could be used as a switch or it could short the circuit out.
How do you increase your talent?
"Talent" is all about Practice, Practice, Practice. But you have placed this question in areas that are more about technology, in which case that's all about study and comprehension.
A 100 ohm resistor is placed across a 100v power source what is the power?
Power dissipated in a resistance = E2/R = (100)2/100 = 100 watts.
Which type of winding use in power transformer?
The transformation ration for a transformer is (Vs/Vp) = (Ns/Np).Which means, Voltage ∞ No. of turns.So, we can say if we have to increase voltage, then we have to increase the no. of turns, and as the no. of turns increase the space between the core and the winding reduce.So, from above we can say that the HV windings are closer to the core than the LV windings.AnswerThere are two configurations for windings in transformers.The first is called 'concentric' or 'tubular', in which the low-voltage windings are placed innermost (i.e. closest to the core) with the high-voltage windings outermost.The second is called 'sandwich', in which the windings are arranged in ring bundles, with alternate rings of high- and low-voltage windings placed one above the other.The first configuration is used with 'core' type cores, with half the LV/HV windings placed around one limb of the core, and the other half of the windings placed around the second limb. The second configuration is used with 'shell' type cores, with the ring bundles placed around the centre limb.
Does a dynamo have mechanical load or does it rotate freely without much efforts like a bearing?
It rotates freely until it is required to do work. As soon as a load is placed across the output more effort will be required to rotate the Dynamo.
Does gas solubility increase decrease or remain the same if a person is placed in the hyperbaric chamber?
The gas solubility in blood increase in a hyperbaric room.
Will the evaporation rate of gasoline increase if placed under pressure?
No, the rate of evaporation will decrease as pressure is increased.
What happens to the mean free path of the molecules in this process if a helium filled balloon initially at room temperature is placed in a freezer will its volume increase decrease or remain the same?
The volume decrease.
Does the spoiler of a car increase or decrease friction between the tires and the road?
The spoiler on a car is meant to create down force on the back or front of a car depending on where it's placed... Which means that yes it does increase friction but it also helps with traction at higher speeds
What patterns are observed left to right across a periodic table?
The electron pattern is the same among elements in a family. This is the reason the periodic table is arranged as it is.
Would a red blood cell increase or decrease in size if placed in a saline solution?
Yes, it increases due to osmosis. The water goes into it, swelling it up and then it bursts with the pressure of too much water.
What substance is placed on a bow to increase friction?
rosin
When does lens convexity increase?
when the degree of convergence of a convex lens placed in air increases, we say its convexity has increased. as the power of a lens is the measure of degree of its convergence or divergence, we can increase the convexity of a lens increasing its powerthis is further achieved by decreasing its focal length.as focal length is inversly proportional to the refractive index of lens we have to decrease in order to increase its convexity.
Can voltage increase or decrease in a system during a day?
Power supply voltages vary with the amount of load placed on them. In many countries the supply voltage has a nominal voltage and a plus or minus tolerance. In the UK the nominal voltage is 230 v but the allowable variation is -6% +10%, in other words 216-253. At my house the voltage is usually between about 236 and 253 volts.
What would happen if you placed the rock in a glass of water?
increase
Why is the voltmeter is placed across the load to be measured?
Because that is what you are trying to measure.
Does the peso sign go before or after the amount?
The Peso sign is placed before the amount.
