Question

according to ohm’s law, which combination of units is the same as the unit for resistance? volt ÷ ampere ampere × volt volt ampere ampere ÷ volt

Answer 1

Volt / ampere

As ohms law states that V=IR which means R = V/I.

Answer 2

Answer : The unit of resistance is ohm and it is equal to volt ÷ ampere.

Explanation :

According to Ohm's law :

$V=I\times R$

or

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

Where,

V is the potential difference or voltage.

I is the current flowing in a circuit.

R is the resistance.

The SI unit of potential difference is Volt. It is denoted as V.

The SI unit of current is Ampere. It is denoted as A.

The unit for resistance is :

$R=\dfrac{volt}{ampere}$

It is equivalent to Ohm or $\Omega$.

Hence, the correct option is (a) " volt ÷ ampere ".
