QUESTION 2
Calculate the length of the resistor of a circular wire used in a heater element connected to a
240V supply and the heater consumes 8 joules of energy in 0,25 seconds. The resistor element
is made of aluminium and it has a uniform cross-sectional area with a diameter of 0,00016
inches.
Hints: linch = 25,4 mm, resistivity of aluminium = 2,825 x 10-6 Ocm
