The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.

What effect does decreased resistance have on a circuit?
resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.
What effect does heat have on electric current flow?
It increases resistance.
How does the loading effect of an ammeter in a low resistance circuit compare to the loading effect in a high resistance circuit?
The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.
How does resistance effect the flow of current in a wire?
Current is inversely proportional to the resistance of the circuit. Resistance goes up, current goes down. Resistance goes down, current goes up.
Heating Effect of Electric Current advantage?
Reliable, simple and safe. Heat can be regulated by changing the resistance in the circuit.
What is the affect of a series circuit on current?
by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .
What happens to a parallel circuit resistance if the voltage applied is doubled?
That has no effect on the resistance. The current doubles also.
How can an ammeter be connected in a circuit and not effect the flow of current?
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
1 What is the effect caused by the ammeter resistance when an ammeter is inserted into a circuit to measure the current?
An ammeter has a finite resistance which is inserted in series with the rest of the circuit, increasing the total resistance and decreasing the current. A good ammeter has a very low resistance, so it shouldn't affect the circuit noticeably.
How can an ammeter loading effect the circuit under test?
Since internal resistance of the ameter will increases the resistance of the circuit. Thus decreasing the current giving an errorenous reading.
What is the effect on current in a wire if both the voltage across it and its resistance are doubled?
it will cause a Short Circuit
