The wiring and connectors that carry the power to a motor must be in good condition. When a connection becomes loose, oxidation of the copper wire occurs. The oxidation . A. acts as an electrical resistance and causes the connection to heat more B. has no effect on the electrical connection C. decreases the resistance D. none of the above

A. acts as an electrical resistance and causes the connection to heat more.

Explanation:

The wiring and connectors that carry the power to a motor must be in good condition. It should be noted that in a case whereby the connection becomes loose, then the oxidation of the copper wire occurs and thee oxidation will act as an electrical resistance and then results in the connection to heat more.

In such case, this has an effect on the electrical connection and increases the resistance. Therefore, the correct option is A.

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
