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.
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.
"Opposition to current" can refer to resistance, reactance, or impedance.
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.
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
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.
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(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.
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.
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Current is proportionally inverse to resistance and when the voltage is fixed, lowering resistance will increase the 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.
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
Increasing resistance decreases current.
Increasing resistance decreases current.
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
