For the same voltage boost, the reactive power capacity

1. more for shunt capacitor
2. more for series capacitor
3. it is same for both series and shunt
4. uncertain

Let Q'_c be t he reactive power of the shunt capacitor, E_r receiving end voltage, X is the line reactance.
Then voltage drop across it

=		Q_c		. X
		E_r

where, Q_c be the reactive power of the series capacitor, then voltage drop across it

sin φ_v =		Q_c		,
		I

where φ_v is the power factor angle.
For equal voltage boost,

Q'_c	X =	Q_csin φ_v
E_r	X =	I

or	Q'_c	=	sin φ_v	=	0.6	= 6
	Q_c		IX/E_r		0.1

Q'_c > Q_c
