What is the relationship between fear and anxiety?
Not really a difference..anxiety is mostly a racing thought process caused by fear..
What is the difference between an ice berg and a glacier?
an ice berg is a chunk off off a glacier and a glacier is a big ice patch caused by snow
Why does a battery not work even though it has a volt reading?
A battery may have a small voltage potential but not the "CAPACITY" to deliver amperage. For instance if you were to measure the voltage at the battery terminals with a Volt/Ohm meter (VOM), you would get a reading of say 12+ volts. As soon as you turn something on such as a headlight or heater motor, the voltage drops down or goes to 0 volts, you would have a battery that is bad or under capacity. It also could be caused by a "BAD CONNECTION" such as a loose battery post clamp. It is critical that when you test a battery, you test it at the battery posts themselves without the cables attached to rule out a bad connection. This is done with a battery load tester. As many people do not have the equipment to test a battery, batteries can be tested at many automotive parts retail outlets across the country for a free charge.
Why can't the potential barrier of a diode be used as a voltage source?
The potential barrier of a diode is caused by the movement of electrons to create holes. The electrons and holes create a potential barrier, but as this voltage will not supply current, it cannot be used as a voltage source.
What are the similarities between UK flood and Pakistan flood?
the uk floods were caused by heavy rain and the river banks burst and the pakistan floods were caused by monsoon rain
How can you get the largest voltage difference?
There is no such thing as a 'voltage difference'! 'Voltage' means 'potential difference', so what you appear to be asking is "How do you get the largest potential difference difference?'! Potential difference is caused by the separation of charges between two points. The greater the amount of charge separation, the greater the potential difference.
What is th potential difference that causes charges to move in a circuit?
The answer is voltage, resistance, electric discharge, and current. It is caused by a difference in energy stability between two points that favors a charge to move down a potential difference.
What causes potential difference?
A potential difference causes an electric current. Think of it like a river : the source of water is the most elevated point of the river, so the water has a lot of gravitational potential energy. The end of the river is the lowest point of it, so the water has very low gravitational potential energy. What happens between these two points? Water flows! This analogy can be applied to electricity; the potential difference is caused, for example, by a battery in an electric circuit.
What is the difference between voltage and emf?
E.M.F: Is the potential difference between two terminals when there is no current i.e. circuit is open, therefore [EMF = OCV].OCV :open circuit voltage.Voltage: Is the potential difference between two terminals when there is current i.e. closed loopAnswerAn e.m.f. (electromotive force) is a voltage or, more accurately, a potential difference ('voltage' is simply another word for 'potential difference'). However, it is the potential difference that appears across the terminals of a supply when it is not connected to its load. When the supply is connected to a load, this potential difference falls because of an internal voltage drop across the supply's internal resistance. So the simple answer is that an electromotive force is a supply's open-circuit terminal voltage.Another definition is obtained from Kirchhoff's Voltage Law, from which we can say that an electromotive force is equal to the sum of all the all the voltage drops around the circuit, including its internal voltage drops.
Is resting potential caused by a difference in the concentration of certain ions inside and outside the cell?
True
A resting potential is caused by a difference in the concentration of certain ions inside and outside the cell?
True
Why KCL in salt bridge minimise liquid junction potential?
A liquid junction potential is a potential difference between two solutions caused by the diffusion of an ion faster than the other. Salt bridges between these solutions containing high concentration of salts (eg. KCl, KNO3, NH4NO3) with ions that diffuse at the same rate minimising this effect.
What is the voltage difference in battery caused by?
Chemical energy is converted into Electrical Energy. Cause: Oxidation , ions
Does non alkaline battery affect the joyo je-32 guitar pickup power supply?
9V DC is 9V DC, no matter what the source. Any difference between batteries is going to be caused by how discharged the batteries are. A non-alkaline battery may discharge more slowly than an alkaline battery, which may lead to a perceived difference when used in the JE-32.
What is the source of electrons in an ordinary electrical circuit is?
The source of electrons in any electrical circuit is provided by an electric potential difference between two points. This potential difference is called voltage, and is measured in volts, or joules per coulomb.Current flow is caused by voltage. Current is measured in amperes or coulombs per second, and is facilitated by outer shell electrons that cascade from atom to atom in conductive materials, such as copper and other metals.
What is the difference between a allergy cold and a regular cold?
One is caused by an allergic reaction, one is caused by a virus
The difference between actual and standard cost caused by the difference between the actual quantity and the standard quantity is called the?
The difference between actual quantity and standard quantity is called the material quantity variance.
