Which statement is true according to Ohm’s law?

We are aware that, according to Ohm's law, the voltage across a conductor carrying current is exactly proportional to the current flowing through the conductor. As a result, the mathematical equation for ohm's law is $V=I·R$ where R is the conductor's fixed resistance at a specific conductor temperature, V is the voltage, I is the current, and now that we have the alternatives analyzed, we can discover the answer. The rule of Ohm is that $V=I·R$, were, $V$ is the voltage, $I$ is the current and$R$ is the conductor's resistance. Voltage and current have a known relationship according to Ohm's law. Hence,$V=I·R$

were
V
whether the voltage,
I
is present-day and
R
is the conductor's fixed resistance at a certain conductor temperature. We can now determine the answer by carefully considering each of the question's possible answers.

Option A: This option asserts that raising the voltage in the circuit will increase current. Now, as mentioned before, in accordance with Ohm's law $I\propto V$, This implies that if the current increases, the voltage will do the same.
As a result, it is the best choice.

Option B: This option asserts that raising the voltage in the circuit would increase resistance. As was previously said, a conductor's resistance is set for a specific temperature. Therefore, increasing the circuit's voltage will not result in an increase in resistance.
As a result, this choice is flawed.
Option C: According to this one, the resistance will rise as the circuit's current rises. As was previously said, a conductor's resistance is set for a specific temperature. Therefore, increasing the current in the circuit will not cause the resistance to rise.
As a result, this choice is flawed. Option D: This option asserts that raising the voltage in the circuit will increase both resistance and current. As was previously said, current increases as voltage increases, but a conductor's resistance is fixed at a certain temperature. Therefore, increasing the voltage in the circuit will not cause the resistance to rise.
As a result, this choice is flawed.
So, choice is the appropriate response (A).

According to Ohm's law, Current is directly proportional to the potential difference provided temperature and all other physical conditions remain constant.

As current is proportional to voltage, as current increases voltage also increases in the circuit.
