SUMMARY

The discussion centers on calculating the resistance of parallel-wired heat wires in a car's back window. Each wire has a resistance of 5.0 ohm/m, with a length of 0.8 m, leading to an individual wire resistance of 4 ohms. However, the total resistance for six parallel connections is stated as 6 ohms, which contradicts the initial calculation. The confusion arises from the principles of parallel resistance, where the equivalent resistance decreases with additional parallel connections.

PREREQUISITES
  • Understanding of electrical resistance and Ohm's Law
  • Knowledge of parallel resistor calculations
  • Familiarity with basic electrical components and their properties
  • Ability to interpret technical manuals and specifications
NEXT STEPS
  • Study the formula for calculating equivalent resistance in parallel circuits

One day when the familiy Jones is out and drives with his new car wonders Oskar why there is a lot of wires in the backwindow. The heat wires are parallelwired where the resistance is resistance free wired.
Oskar and his father reads in the instructionsbook that the wires got a resistance 5.0ohm/m they are connected six times parallely and the length of each wire is 0.8 m

Then I get the resistance for each wires is 0.8*5 = 4 Ohm

But This is not the answer, the book says that the answer should be 6Ohm because two wires creates a parallelwiring with resistance 4 Ohm in every turn and 2Ohm as replacementresistance

Can someone please explain to me how to do this ? :zzz: :zzz: :zzz: :zzz:

Im really stuck...

Thx

I do not understand the statement of your problem.

Post your native language, perhaps there is someone here who could help you get a better translation.
