General Phusics paper 6 question

[danial_ameen]

This is just s general question whenever they ask draw a voltmeter to show the voltage
of all the n resistors( parallel connection) where should we draw it on the power source or beneath the last resistor


Another problem is in Nov 2006 p6

Ci) the question states that we should find the actual volume of the 10 rods because the previous equation used was for a cylinder
pls help me

about the voltmeter , No idea ... =.="

however about the rod volume , it said that it was round 5 turns about the rods , marking the beginning and the end , you take the result which is 24.5 , divide it by 5 , it will give you the circumference of the bundle , now all what you have to do is to follow the equation , V =( 4.9^2 × 4.1 )/(4Pi) = 7.833685876 cm^3 ,

can u help me with the same question part C
ESTIMATE THE TOTAL VOLUME OF RODS ???

 

[SuperXDE]

Abdullah , Habeeby , Look on the Post I just posted , the volume is mentioned already...

Thanks superXDE
VOLTMETER IS BENEATH THE RESISTOR

voltmeter is always in parallel so if given series ciruit u need to draw a parallel below it to include the voltmeter in the circuit.
