ATT TEST 2 2026 EXAM SCRIPT COMPLETE Q
AND A STUDY GUIDE 100% CORRECT
⩥In which direction does current flow? - Negative to positive
⩥Current is the ____ throughout whole circuit - Same
⩥4 steps of troubleshooting - Analyze, check setup, calculate/measure,
check results
⩥An open series component drops _____ volts - Applied
⩥Resistance is how much over open component? - Max or infinite
⩥Short provides how much resistance? - No resistance
⩥Shorts read how many volts? - 0 volts!!!
⩥Is current or volts the same at all points in parallel circuit? - Volts.
Each branch reads applied volts
⩥Open components in parallel branch have how much current? - 0 A
, ⩥Current is (blank) with an open in parallel branch - Lowered
⩥What happens to current with a short in parallel branch? - Increases to
MAX
⩥Opening what series-parallel component will cause amps to be 0? -
Series component. Volts dropped across open
⩥Current (increases/decreases) if a parallel component opens in series-
parallel - Decreases
⩥With open in parallel branch of s-p circuit: series volt
drops(increase/decrease) and parallel volt drop (increase/decrease) -
Decrease, increase
⩥Current increases or decreases with short in series component (s-p
circuit) - Increases
⩥What happens to REQ when there is a short in a parallel branch (s-p
circuit) - Goes to 0 ohms (parallel volt drops are 0 volts)
⩥What happens to circuit values when a load is addedto voltage divider?
- Resistance down, voltage down, current up
