Find the odd one ?( I ^{2} R t , VIt , V ^{2} t / R , V ^{2} R / t )

Question

Find the odd one ?

\[ \left( I ^{2} R t , VIt , V ^{2} t / R , V ^{2} R / t \right) \]

Answer 1

(i) I²Rt

(ii) VIt

\(\because\) V = IR

I²Rt

(iii) \(\frac{V^2t}R\)

= V = IR

 = \(\frac{I^2R^2t}{R}\)

 = I²Rt

(iv) \(\frac{V^2R}t\)

\(\because\) V = IR

\(\frac{I^2R^2R}t\)

\(=\frac{I^2R^3}t\)

This is odd.
