Question 1 A wire has a resistance of 10.0 0, a radius of 4.11 mm and a length of 4.00 m and we want to nd out what material it is made out of. One way to do this is to calculate the resistivity of the material. Calculate the resistivity of the material used for this wire. 0.000133 0m 0.000123 0m 0.000266 Om 0.000143 0m Question 2 The gure shows a battery connected to two resistors in series. What is the power dissipated across each resistor? R1 = 90.0 0, R2 = 4.90 O and V= 14.0 V. The power dissipated by R1 is 817 W and the power dissipated by R2 is 0.107 W The power dissipated by R1 is 1.96 W and the power dissipated by R2 is 0.107 W The power dissipated by R1 is 817 W and the power dissipated by R2 is 44.5 W The power dissipated by R1 is 1.96 W and the power dissipated by R2 is 44.5 W Question 3 b Calculate the equivalent resistance of the resistors shown in the figure. re.I = 27.0 0, R2 = 10.0 0, R3 = 49.0 0, R4 = 43.0 0 and R5 = 21.0 0. 13.0 D 26.5 D 18.1 D 150
