Current Attempt in Progress Wire C and wire D are made from different materials and have length Lc = LD = 1.7 m. The resistivity and diameter of wire Care 3.7 x 10-6 Q-m and 1.34 mm, and those of wire D are 3.1 x 106 :m and 0.75 mm. The wires are joined as shown in the figure and a current of 3.6 A is set up in them. What is the electric potential difference between (a) points 1 and 2 and (b) points 2 and 3? What is the rate at which energy is dissipated between (c) points 1 and 2 and (d) points 2 and 3? Lc 2 -Lp (a) Number i Units (b) Number i Units (c) Number i Units (d) Number i Units eTextbook and Media

kenney works at an iron manufacturing plant. he make a piece of iron that has a resistivity of: 1.0 x 10-7-m this iron piece is in the shape of a truncated cone. help kenney calculate the resistance between the two circular ends of the cone. 2.00 cm 20.0 cm 4.00 cm

E28. According to a safety code, the maximum allowable current for a 14 gauge copper wire (diameter, 1.628 mm) is 15 A, and it is 5 A for an 18 gauge wire (diameter 1.024 mm). What would be the potential difference between the ends of a 10m length of each type of wire for maximum current? ∆V14 = 1.23 V ; ∆V18 = 1.03 V Please show steps and formulas for my own understanding.
