Match List-I with List-II

	List-I		List-II
(A)	Angular Impulse	(I)	[M0 L2 T–2]
(B)	Latent Heat	(II)	[ML2 T–3 A–1]
(C)	Electrical resistivity	(III)	[ML2 T–1]
(D)	Electromotive force	(IV)	[ML3 T–3 A–2]

Choose the correct answer from the options given below : 

Angular Impulse

• Angular impulse = Torque × Time
• Torque = Force × Distance = $(MLT^{-2}) \times L = ML^2T^{-2}$
• Time = $T$
• Dimensional formula of Angular Impulse = $ML^2T^{-1}$
• (III) [ML²T⁻¹]

Latent Heat

• Latent heat = Energy/Mass
• Energy = Work = Force × Distance = $(MLT^{-2}) \times L = ML^2T^{-2}$
• Mass = $M$
• Dimensional formula of Latent Heat = $L^2T^{-2}$
• (I) [M⁰L²T⁻²]

Electrical Resistivity

• Resistivity ($\rho$) = Resistance × Length / Area
• Resistance $R$ = $V/I$
• Using Ohm’s Law: $V = IR$
• Voltage $V$ = Work/Charge = $ML^2T^{-3}A^{-1}$
• Current $I$ = Charge/Time = $AT^{-1}$
• Resistance $R$ = $V/I = ML^2T^{-3}A^{-2}$
• Resistivity = $R \times L$
• Dimensional formula of Electrical Resistivity = $ML^3T^{-3}A^{-2}$
• (IV) [ML³T⁻³A⁻²]

Electromotive Force (EMF)

• EMF is essentially voltage, and its dimensional formula is:
• (II) [ML²T⁻³A⁻¹]

(A) → (III), (B) → (I), (C) → (IV), (D) → (II)
