Question

soldered connections provide a
a current gain.
b voltage boost.
c physical bond and excellent insulation.
d physical bond and conduction of electricity.
click the button or type the letter next to your answer.

Explanation:

Soldered connections are used to join components. Solder creates a physical bond between parts. Also, solder is a conductor, so it allows electricity to flow (conduction of electricity). Option A is wrong as soldering doesn't provide current gain. Option B is wrong as it doesn't boost voltage. Option C is wrong because solder is conductive, not an insulator. So the correct option is D.

Answer:

D. physical bond and conduction of electricity.
