Answer: Making conducting wires.
- A Making resistors
- B Electrical insulation
- C Making conducting wires
- D Making capacitors
Correct answer: C. Making conducting wires
Explanation: Electrical conductors (silver, copper, aluminum) have very low resistivity: good for wires to minimize energy loss.
In series, the same current flows through both resistors; in parallel, the current splits between branches and the voltage across each resistor is the same.
Concept context
Ohm's law, resistors, Kirchhoff's laws, Wheatstone bridge, and cells.
