Question

Which of the following statements are true.

A) A short to ground causes decreased current flow
B) an open causes unwanted voltage drops
C) high resistance problems cause increase current flow
D) both open in high resistance problems may cause a load not to work

Answer 1

1 ) false

2 ) true

explanation

short circuits may occur between two phases, between a phase and neutral or between a phase and earth (ground). Such short circuits are likely to result in a very high current and therefore quickly trigger an overcurrent protection device.

3 ) FALSE

4 ) TRUE
