How the declair one ohm resistance?
One ohm is the resistance through which a current of one ampere will induce an electrical potential difference of one volt. Ohm's Law: Resistance is Voltage divided by Current
Why is the potential difference between two points in a good conductor so small that it can be neglected?
Potential difference V = I R. Here I is the current passing through the conductor. R is the resistance of the conductor. In case of good conductor the resistance will be almost zero and so the product too becomes almost zero. Hence the potential difference is neglected.
What is the difference between resistance and resistor?
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors
True or false current is the voltage multiplied by the resistance?
False. Voltage (E) is the potential difference, i.e. electrical potential, in joules per coulomb. Current (I), on the other hand, is electrical charge flow, in coulombs per second. The two units are not related except through a common term such as resistance (R). E = IR I = E/R R = E/I
How much current flows through a resistor of 285 ohms if the potential difference across the resistor is 122 volts?
Use Ohm's Law, i.e., V=IR here, V=voltage I=current R=resistance
How can one determine the potential difference in a circuit?
To determine the potential difference in a circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). By measuring the current flowing through the circuit and knowing the resistance of the components, you can calculate the potential difference.
What will be the potential difference across a 50Ω resistor if a current of 500mA is flowing through it?
Potential difference equals current multiplied by resistance or E = IR therefore the answer to your question is 25 volts
What happen is the potential difference across is double?
If the potential difference across a circuit is doubled, the current flowing through the circuit will also double, assuming the resistance remains constant. This is because Ohm's Law states that current is directly proportional to voltage when resistance is held constant.
One way to make current is to use a what?
You can apply a potential difference across a wire to cause a current to flow through. Ohm's Law allows you to calculate the amount of current based on the voltage supplied and the resistance of the circuit. I = current V = voltage or potential difference R = resistance I = V/R
How the declair one ohm resistance?
One ohm is the resistance through which a current of one ampere will induce an electrical potential difference of one volt. Ohm's Law: Resistance is Voltage divided by Current
When the current traveling through a resistor is increased what happens to the voltage that travels through the same resistor?
Your question reveals fundamental misunderstandings about the nature of electricity.'Voltage' is simply another word for 'potential difference', and a potential difference appears across opposite ends of the resistor; it doesn't 'travel through' that resistor! Current, on the other hand, DOES 'travel through' the resistor and is caused by the potential difference across the resistor.Resistance is the ratio of potential difference to current. So if the resistance remians unchanged when the current through it doubles, then it has happened because the potential difference has doubled.
How to find the potential difference across a resistor in an electric circuit?
To find the potential difference across a resistor in an electric circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). So, you can calculate the potential difference by multiplying the current flowing through the resistor by the resistance value of the resistor.
Potential difference across resistor is doubled?
If the potential difference across a resistor is doubled, the current flowing through the resistor will also double, assuming its resistance remains constant. This relationship is described by Ohm's Law, where current is directly proportional to voltage when resistance is held constant.
What is the relationship between the current flowing through a wire and the potential difference across it?
The relationship between the current flowing through a wire and the potential difference across it is described by Ohm's Law. Ohm's Law states that the current (I) flowing through a wire is directly proportional to the potential difference (V) across it, and inversely proportional to the resistance (R) of the wire. Mathematically, this relationship is represented as V I R.
How can you calculate the potential difference between two points in a circuit?
To calculate the potential difference between two points in a circuit, you can use Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). The formula is V I x R. By knowing the current flowing through the circuit and the resistance between the two points, you can calculate the potential difference.
When the potential is high the current passing through a conductor it is also high true or false?
I think you mean when the 'potential difference' is high, is the current also high? The answer is that it depends on the impedance (a.c.) or resistance (d.c.) of the circuit. If this remains constant, then raising the potential difference will cause the current to increase too.
8 If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V the current flowing through the circuit is?
There is a simple equation relating voltage (properly potential difference), current and resistance: V=IR Where V=potential difference, I=current and R=resistance So to answer: I=60/12 I=5
