My interpretation of that description is of a milliammeter in series with a resistor, and the voltmeter connected across that combination of meter + resistor such that the voltmeter measures the sum of two voltages VA + VR.
I don't really get what you mean here. Did u mean that I should...
Hi there, this is one of the question of my assignment.
A voltmeter with a sensitivity of 1000 Ω/V has a full scale deflection of 150V. When connected across an unknown resistor in series with a milliammeter, it reads 100V. If the milliammeter reads 50mA, calculate the following:
a...
u = (a, (sqrt(6)/2)a, c)
v = (f, (sqrt(6)/2)f, e)
u + v = ( a + f, sqrt (6 ) ( a+f) , c+ e )
a+f = sqrt(6) ( a+f ) ??
as for multiple part,
k(a, (sqrt(6)/2)a, c) =(ka, ka (sqrt(6)/2), kc)
ka = ka (sqrt(6)/2), hence subspace S is the subset or R3?
ok...I start to understand a little bit d...
if I substitute inside just like wad u say mark, I find that it is weird,
the equation I try :
sqrt (3) x = sqrt (2 ) y
sqrt (3)/ sqrt (2 )x = y
u = ( 1, sqrt(3)/sqrt(2) 1 , c )
v = ( 2, sqrt(3)/sqrt(2) 2 , d )
u + v = ( 1, sqrt(3)/sqrt(2) , c...
R3 Subspace - Urgent
Homework Statement
Prove that S={(x,y,z):\sqrt{}3 x=\sqrt{}2 y is a subspace of R3
I'm really confuse with this and I still don't know how to proved it.
Can anyone help me with this?
I really a newbie in this. ><
