Using Pythag Theorem
sqrt ( 20^2 + 48^2) = 52 ft
NO.......
Current in the circuit v/r = i
45/(20+30+45) = 473 mA
Votage across R3 = IR = .473 * 45 = 21.3 v
ALL of the voltage will be dropped around the circuit .....45 v will be dropped
R3 portion will be a fraction 45 / (20+30+45) x 45 v = 21.3 v
it would be 45.0 right?
For this circuit, what will be the voltage drop across R3 ?
21.3 V
14.2 V
45.0 V
9.47 V
i meant this one
No, there is an obvious pattern in the plot.
The residual value for x = 3 is -1.5 because the dot is 1.5 units below the graph.
ops im sorry i submitted the wrong one!
The residual at 1 is -2.
The residual at 2 is 2.
The residual at 3 is -1.5.
etc.
The fourth graph expresses this.
thank you for your explaination, i really understand it!
TRUE !! Keeping it simple .... and potentiometers can be used as rheostat....
(1 - 2) + (3 - 4) + (5 - 6) + ... + (2003 - 2004) + (2005 - 2006) + 2007
= -1 + -1 + -1 (for 1003 term) + 2007
= -1003 + 2007 = 1004
oh okay, yes that makes sense!!! im sorry i got a bit confused.
We already determined the current through the circuit (in a previous question)
I R4 = Voltage R4 = 5 ohms and current was from previous Q
A potentiometer also divides the current flow. A device that does nothing else except vary the resistance is a rheostat.
All the terms from 10! have 2*5*10 = 100 as a factor so none of these will affect the last 2 places in the sum
So I only need the last 2 places of 5!
The last place will be 0 (2*5)
1*2*3*4*5 = 120
So the last 2 digits are 20
R1 > R2
Resistance of 1 is greater than Resistance of 2
The higher the resistance, the more it resists the flow of current.
So less current will be able to flow through the larger resistor.
I2 > I1
thank you so much for yuor help!!
R2 is the smaller and thus I2 will be the larger
Oh fun! (:
45,600 - 43,000 = 2,600 at 40% = 2,600 x 0.40 = 1040.00
43,000 - 11,000 = 32,000 at 20% = 32,000 x 0.20 = 6400.00
No tax below 11,000.
1040.00 + 6400.00 = 7440.00
ops looks like A is imconplete sorry,
so it would then be I 2 < I1 ?
Angle(w) will equal one-half of teh intercepted arc.
Angle(w) = ½·246o = 123o.
Sure! Just hangin' at the house makin' beer......
HINT: For parallel circuit resistors .....(they all have the same voltage applied across them) the smaller the resistor, the larger the current
Awesome! thanks (:
