=__**MR DOWNES' SET 1 HOMEWORK DUE MONDAY 6TH OCTOBER DURING PERIOD 2. YOU WILL HAVE ABOUT TEN MINUTES TO FINISH OFF AT THE START OF THAT LESSON BOYS.**__=


 * PLOT THE DATA ATTACHED BUT ONLY CHOOSE ENOUGH POINTS TO DRAW DECENT CURVES ON THE SAME SIDE OF GRAPH PAPER. MAKE SURE YOU LABEL EACH CURVE CLEARLY AND UNAMBIGUOUSLY PLEASE BOYS.**


 * WHEN YOU DO THE BAR CHART (WITHOUT SPACES BETWEEN) LEAVE OUT D & E.**


 * WE WILL HAVE ABOUT 15 MIN ON THE MONDAY TO FINISH OFF IF NECESSARY BUT BE MOSTLY DONE BY THEN PLEASE.**

 * MR D **

BE CAREFUL SINCE THE 'U' VALUE WHICH IS REFERRED TO IS IN 'W / square / K ' AND THE LAST 'K' IN THIS REFERS TO THE DEGREE 'KELVIN' AND THIS IS EXACTLY THE SAME SIZE AS THE DEGREE CENTIGRADE WHICH YOU ARE FAMILIAR WITH SO THEREFORE:-

a U value of say 370 W/square meter/K is EXACTLY the same as 370 W/square meter/degree C. This means that 370 of heat  is lost per second per square meter per degree C DIFFERENCE in temperature across the Window (for example - if it is quoted for a window).

THE THREE DOCUMENTS BELOW STATE THE PROJECT AIM AND SOME HELP WITH DATA ETC FOR YOU TO USE UNLESS YOU WISH TO USE YOUR OWN IN PLACE. YOU OBVIOUSLY NEED THE FIRST DOCUMENT SINCE THIS STATES THE PROJECT AIM.

ADDITIONAL INFORMATION FOR YOUR USE GENTS. REMEMBER TO QUANTIFY YOUR STATEMENTS WHERE EVER POSSIBLE. REFER TO DOCUMENTS. YOUR A4 OF PAPER FOR HOMEWORK MUST BE IN  LESSON - FRIDAY 21ST MARCH PERIOD 4. I WILL ALSO SHOW YOU (BRIEFLY) THE DELAYED DEMOS FROM THE CIRCUS WHICH MALFUNCTIONED LAST TIME I TRIED IT. NOW.

FOR THE ATTACHED GRAPH OF VOLTAGE VERSUS CURRENT FOR A THERMISTOR:-

a) CALCULATE THE RESISTANCE (REMEMBER R = V / I NOT GRADIENT!!!!). WRITE DOWN ALL YOUR CALCULATIONS OF R = V / I FOR THE POINTS LABELLED A,B,C,D, AND E ON THE RIGHT HAND SIDE OF THE ATTACHED GRAPH PAPER SHOWING THE ACTUAL VALUES DIVIDED AND THE ANSWERS IN OHMS. YOU WILL NOTICE THAT THE VOLTAGE VALUES ARE ALL 4 VOLTS FOR THESE POINTS AS YOU <span style="background: none !important; border-image: none !important; border: currentColor !important; display: inline-block !important; float: none !important; font-size-adjust: none !important; font-stretch: normal !important; font: 13px/19.5px arial,helvetica,sans-serif !important; height: auto !important; margin: 0px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-decoration: underline !important; text-indent: 0px !important; vertical-align: baseline !important; width: auto !important;"> ACROSS THE GRAPH FO RINCREASING CURRENT VALUES.
