When the resistance in a circuit remains constant, just how are the voltage and current related? the present doubles as soon as the voltage doubles due to the fact that they are straight proportional. The current doubles when the voltage doubles since they space inversely proportional.
You are watching: When the resistance in a circuit remains constant, how are the voltage and current related?
The correct answer is the present doubles when the voltage doubles due to the fact that they are directly proportional.
From ohm"s law we understand that at consistent temperature and also pressure, the existing flowing v a wire is straight proportional come the potential difference throughout the two ends that a conductor.
Mathematically V ∝ I
⇒ V = IR
Here, R is called as the resistance of the conductor, V is the voltage, and also I is the current.
As every the question, the resistance is preserved constant.
Hence, if current is doubled in the circuit, then voltage is likewise doubled as current and also voltage are straight proportional to each other.
1. The existing will drop to fifty percent of its initial value.
The trouble can be solved by utilizing Ohm"s law:
V is the voltage across the circuit
R is the resistance that the circuit
I is the current
We deserve to rewrite it as
In this problem, us have:
- the resistance the the circuit continues to be the same: R" = R
- the voltage is reduced to fifty percent of its original value:
So, the new current will certainly be
so, the present will fall to half of its original value.
After all that effort, you never told united state what kind of circuit "... This form of circuit ..." is referring to.
After scanning the perform of choices, my hunch is that you"re introduce to a parallel circuit, and also that the correct choice is ( A ) .
I might be wrong.
