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 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 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 will happen to the current if the resistance is decreased?
If resistance is decreased, the current will increase according to Ohm's Law. This is because current is directly proportional to voltage and inversely proportional to resistance. Lower resistance allows more current to flow for a given voltage.
How calculate unknown resistance?
To calculate an unknown resistance, you can use Ohm's Law, which states that resistance (R) equals voltage (V) divided by current (I). You can measure the voltage across the unknown resistance using a multimeter and the current flowing through it using an ammeter. Then, you can divide the voltage by the current to calculate the resistance.
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)
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.
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 the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
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
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 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.
How does the increasing the resistance affect the current?
Increasing resistance decreases current.
How does increasing the resistance affect the current?
Increasing resistance decreases current.
When resistance is in a circuit what happens to the current?
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
