Question

According to Ohm’s law, which is stated as I = V ÷ R, which two sentences are true? If the current increases, then the resistance increases. Assume voltage is constant. If the resistance decreases, then the current increases. Assume voltage is constant. If the voltage increases, then the resistance decreases. Assume current is constant. If the voltage increases, then the current increases. Assume resistance is constant. If the voltage increases, then the current decreases. Assume resistance is constant.

Answer 1

If the voltage increases, then the current increases. Assume resistance is constant. And If the resistance decreases, then the current increases. Assume voltage is constant. Is the correct answer

Answer 2

Explanation :

According to Ohm's law :

V =IR

Where

I is the current flowing

R is the resistance of the wire

V is the potential difference

$I=\dfrac{V}{R}$

If V is constant :

k = IR

$I=\dfrac{k}{R}$

if I increase, then R decrease. So, option (2) is correct.

If R is constant :

$k=\dfrac{V}{I}$  

There is an inverse relation between the voltage and the current.

So, If the resistance decreases, then the current increases. Assume voltage is constant.

If the voltage increases, then the current decreases. Assume resistance is constant.
