Is volt the SI unit for voltmeter?
No it is not. A volt is a joule divided by a coulomb, it is m2∙kg∙s−3∙A−1
What parts of a light bulb are conductors or insulators?
The conductors are the two wires you see supporting the filament. The glass supporting all this is an insulator. The metal ring around the base and the very bottom of the bulb conduct the electricity into the bulb. The plastic between them is an insulator. --- In incandescent bulbs, the filament of the bulb is a conductor, but has a high resistance to the flow of current, causing it to heat up and glow. In fluorescent bulbs, the gas in the tube resists the flow and is ionized. The ultraviolet photons that it gives off cause the inside of the tube (coated with phosphors) to glow.
How much work is done when one coulomb charge moves against a potential difference of 1 volt?
That is 1 Joule of energy. If it happens in 1 second, 1 amp would have flowed during that time. The same amount of work (energy) is done by moving a force of 1 Newton through a distance of 1 metre.
When a high-energy bond of ATP is broke primarily what happens to the released energy?
The fact that the atoms get apart (against a force that attracts them) means there is potential energy.The fact that the atoms get apart (against a force that attracts them) means there is potential energy.The fact that the atoms get apart (against a force that attracts them) means there is potential energy.The fact that the atoms get apart (against a force that attracts them) means there is potential energy.
When potential energy turns into electrical energy which form of energy does potential first become?
Potential energy becomes static energy in the form of a difference of potential energy between two bodies, or clouds of charged particles. For instance the motion of any object against another object causes particles to become statically charged. That is potential and electrical. Once an electrical path is found between those fields the electrical force becomes similar to kinetic force and this is current.
What is difference between corrosion resistance and oxidation resistance?
corrosion resistance is resistant against chemicals oxidation resisstance is restant against oxigen
What is the difference between an insurgency and a resistance?
Insurgency is an act of rebellion against a constituted authority whereas resistance is a group of people who are dedicated for resisting foreign occupation or an invasion. The main difference is that insurgency does not involve resistance against foreign invasions but only against the same nation in which they are located.
Why does the filament lamp does not follow Ohms Law give any example?
Well, honey, the filament lamp doesn't give a hoot about Ohm's Law because its resistance changes with temperature. As the current increases, the temperature of the filament rises, causing the resistance to also increase. It's like trying to control a wild horse - good luck getting it to follow any law!
Is volt the SI unit for voltmeter?
No it is not. A volt is a joule divided by a coulomb, it is m2∙kg∙s−3∙A−1
Why is a graph of voltage against current for a filament bulb curved?
Because as current increases, heat increases and therefore resistance increases. Since resistance is the gradient of the graph, the gradient will increase and therefore the graph will curve. (The filament in the bulb is an non-ohmic conductor; its resistance is only constant at a constant temperature.)Another AnswerIncandescent lamp filaments are manufactured from tungsten. Tungsten is classified as 'non-ohmic' or 'non-linear', which means that (in common with most materials, in fact) it does not obey Ohm's Law. For a material to obey Ohm's Law, the ratio of voltage to current (i.e. its resistance) must remain constant for variations in voltage -as you have discovered, tungsten doesn't do this, producing a curve, rather than a linear, graph. As the original answer indicates, the temperature coefficient of resistance of tungsten in such that, as it gets warmer, its resistance increases.Those few materials that do obey Ohm's Law are called 'ohmic' or 'linear' materials.
Which one is right resistance against or to?
Both "resistance against" and "resistance to" are commonly used and generally correct. "Resistance against" is often used when describing something actively opposing or fighting against resistance, while "resistance to" is used when describing something's ability to withstand or endure resistance. Both phrases can be correct depending on the context in which they are used.
What is potential difference or voltage?
If you take two different nodes in a network and if you find the difference in voltage for those nodes then it is known as potential or voltage difference. Here the reference is not taken. But if you find potential difference between a node and its respective ground it is known as voltage at that node here reference is ground potential i.e zero.Answer'Voltage' is synonymous with 'potential difference'; they both mean the same thing. And it is important that these terms are not confused with 'potential'. So, it is incorrect to say 'voltage difference' (which would mean 'potential difference difference'!), or to describe a voltage as existing 'at' a particular point, or 'with reference to', for example, earth or ground.In very simple terms, if two points are at different potentials, then there is a potential difference (or 'voltage') between them. A potential exists when work is done moving a charge to a particular point; the greater the work, the higher the potential. 'Potential' is roughly equivalent to the potential energy gained by an object when it is lifted against the force of gravity.Think of it this way: 'potential' is equivalent to 'height', whereas 'potential difference' (voltage) is equivalent to the difference between points at different heights.
When you do resistance exercise you work against what resistance?
Weight
What is system resistance?
The resistance the heart has to pump against
Is the after load the resistance what the ventricle in the heart has to contract against?
The resistance against which the ventricle contracts is know as afterload.
What does potential diffrence mean?
Potential Difference is the difference in electric potential energy per coulomb of charge at one point of a circuit compared to the charge at another point in a circuit. Potential difference, or voltage, is a way of describing the energy of an electric field without using test charges. In circuits, potential difference is the difference in voltage from one part of a circuit to another. It can also be described by ohms law where the Voltage=Current*Resistance In electrostatics, potential difference is the line integral of the electric field from one point to another with respect to distance.
When you do resistance exercise you work against the resistance or blank of an object?
