What happens to a circuit's resistance (R), voltage (V), and current (I) when you increase the length of the wire in the circuit?


A. R is constant.
V increases.
I increases.

B. R increases.
V decreases.
I decreases.

C. R decreases.
V is constant.
I increases.

D. R increases.
V is constant.
I decreases.

Please be careful trying to find the answer here, there are 4 different versions of this same exact question.

Respuesta :

R increases, V is constant and I decrease when you increase the length of the wire in the circuit. Option D is correct.

What is ohm’s law?

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

When all physical parameters and temperature are constant, Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

This current-voltage connection may be expressed mathematically as,

The Equation of Ohm's Law

V=IR

The resistance of the circuit is;

[tex]\rm R= \rho \frac{L}{A}[/tex]

When you increase the length of the wire in the circuit, R increases, V is constant and I decrease,

Hence, option D is correct.
