How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
How many amperes of current will flow in a circuit if the voltage difference is 9 V and the resistance in the circuit is 3 Ω?
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
What statement that current is equal to the voltage difference divided by resistance?
V = IR The amont of current passig through a conductor is directly proportional to potential differenxe v applied across its end provided the temperature & physical state doesn't change..!!thanks
What is the relation between voltage and current?
Voltage and current are two different things. Voltage is the electric potential difference between two points. Expressed in volts, it is also joules per coulomb. Current is the charge flow past a point. Expressed in amperes, it is also coulombs per second. You can relate voltage and current using Ohm's Law, which states that voltage is equal to current times resistance. Resistance is, therefore, equal to voltage divided by current. Using base units, resistance is equal to joules per coulomb divided by coulombs per second, which simplifies to joule-seconds per coulomb squared. That is a difficult unit to write, so we just use ohms as the unit.
How does electrical resistance change the current in a circuit?
Electrical resistance is opposition to electric current flow. There is a resistance to the flow of current. And a "balance" between applied voltage and resistance determines how much current will flow in a circuit. For a given applied voltage, if we increase the resistance, the current flow will decrease. For that same applied voltage, if we decrease the resistance, the current flow will increase. It's a simple relationship, and it is set down by the following expression: E = I x R We can also write it as I = E / R and R = E / I Voltage (in volts) is E, current (in amps) is I, and resistance (in ohms) is R. In the first expression, voltage is equal to current times resistance. For a constant voltage, any increase in resistance will cause a decrease in current flow. And any decrease in resistance will cause in increase in current flow. Just as cited earlier.
Voltage muiltiplied by resistance measures to current?
No. Voltage divided by resistance is equal to current.
What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
The statement that current is equal to the voltage difference divided bythe resistance in known as?
Ohm's Law V = I R Voltage = Current x Resistance
Does voltage divided by watts equal the current?
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
What does power divided by speed equal?
Ohm so correctly said: Voltage divided by current equals resistance. Voltage divided by current will tell you the value of a circuit's resistance. But resistance is not affected by either voltage or current. It is determined by the length, cross-sectional area, and resistivity (type of conducting material) of the conductor. Resistivity is, in turn, affected by temperature. So voltage divided by current tells you what the resistance happens to be - changes in voltage or current do not affect resistance.
Is current the voltage multiplied by resistance?
No. V =Voltage, I =current, and R =resistancein the simple equation: V=I*R. As well, V/I=R, and. V/R=Iso Current is voltage divided by resistance
What is the statement current is equal to the the voltage difference divided by the resistance know as?
Ohm's law.
What is current is equal to the voltage difference by the resistance?
Ohm's Law: Current is voltage divided by resistance.Alternative AnswerIf, by 'statement', you are referring to a 'law', then there is no electrical law that states that 'current is voltage divided by resistance'.The relationship between voltage, current, and resistance is derived from the definition of the ohm, which is defined in terms of a volt per ampere, which can be manipulated to say that 'current is equal to voltage divided by resistance'.This is frequently, but incorrectly, described as being 'Ohm's Law', but Ohm's Law isn't universal and it only applies to a very limited range of linear (or 'ohmic') loads, whereas 'resistance is voltage divided by current' applies to allloads (linear or non-linear) at any given value of voltage.
The statement, current is equal to the voltage difference divided by the resistance, is known as?
Ohm's Law. It is usually written as V = I x R or in words Voltage is equal to Current times Resistance; or in your terms I = V / R.
Is current a measure of the flow electrons through a circuit?
I believe so. It is also equal to power divided by voltage, as well as voltage divided by resistance.
How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
What happen to the current when the voltage is greater than or equal to 6 volts?
The current is greater than or equal to (6) divided by (the effective resistance of the circuit).
