SOLUTIONS 2025/2026
Amperes - correct-answer-The rate of electron flow, the unit for measuring
electrical current; the abbreviation is amp.
decreases - correct-answer-When the frequency of the applied voltage increases
capacitive reactance increases, decreases, or remains the same.
45 degrees out of phase - correct-answer-If the AC voltage reaches its positive
maximum at the same time as current reaches 0, voltage and current are said to
be__________
.025 seconds - correct-answer-If a resistor of 5 mega ohms is placed in series with
a capacitor of .005 micro farads, the time constant would be__________
maximum - correct-answer-A multi-meter should offer maximum or minimum
resistance.

Decreases - correct-answer-As the resistance of a material increases, its
conductance increases or decreases.
Capacitors block DC, Capacitors can store a DC charge, Capacitors pass the effects
of AC - correct-answer-Except for a brief period immediately after voltage is
applied_________
