If you measure zero current, then there are two possibilities,
and there's no way you can tell which one is true without
another measurement.
-- The voltage across the circuit may be zero,
and the resistance could be anything.
-- The resistance of the circuit may be infinite,
and the voltage could be anything.
What else can I help you with?
If resistance goes up how is current affected?
If resistance goes up in a circuit, the current will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, meaning that as resistance increases, current decreases.
The opposition of current is called?
"Opposition to current" can refer to resistance, reactance, or impedance.
What is the role of resistance in an electric circuit and how does it affect the flow of current?
Resistance in an electric circuit is the opposition to the flow of electric current. It is measured in ohms. Resistance affects the flow of current by reducing it, as higher resistance leads to lower current flow. This relationship is described by Ohm's Law, which states that current is inversely proportional to resistance in a circuit.
What is the relationship between the voltage and the current when the resistance is kept constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
What is the relationship between resistance and current for a given voltage?
Ohm's Law states that the relationship between resistance, current, and voltage is given by the equation V IR, where V is the voltage, I is the current, and R is the resistance. This means that for a given voltage, the current flowing through a circuit is inversely proportional to the resistance - as resistance increases, current decreases, and vice versa.
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
What is meant by resistance of a current?
The resistance of a current is a measure of how difficult it is to push the electrons along.AnswerThere is no such thing as the 'resistance of a current'. Resistance is a characteristic of the material through which a current flows, not of the current itself.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Why do the resistance is zero in case of short circuit?
The current is 0. Current is the unit of flow of electrons in a circuit, and in an open circuit, electrons cannot flow. Therefore there is 0 current. Another way to look at it is that I = V / R, where I = Amps (current), V = voltage, and R = resistance (impedance). In an open circuit, the impedance is infinite, and by using our math skills, we know that X (or V in our case) divided by infinity, is 0. I = V / Infinity = 0
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Does lowering resistance increase current?
Current is proportionally inverse to resistance and when the voltage is fixed, lowering resistance will increase the current
How does loading effect affect flow of current?
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
Is fet having negative resistance?
JFET BFW20 shows negetive resistance when gate is grounded (VGS = 0) and vary Drain to source voltage and measure Drain current. As the voltage is increased, the drain current decreases. Prof.S.Lakshminarayana.
How does increasing the resistance affect the current?
Increasing resistance decreases current.
How does the increasing the resistance affect the current?
Increasing resistance decreases current.
