Question

What is watt to

• A. $A\Omega$
• B. $A²\Omega$
• C. $A\Omega ²$
• D. $A\Omega ²s⁻¹$

Answer 1

The correct option is B

$A²\Omega$

We have the power formula as given below

$P=IV$

We also know from Ohm's law, that $V=IR$

So $P=I²R$

Now putting units for the quantities

$Watt=A²\Omega$

$A=$ ampere unit of current

$\Omega =$ohm unit of resistance

Thus, the correct answer is option (B) i.e. $A²\Omega$.
