NCATT-AET ACTUAL EXAM TEST BANK 300+ QUESTIONS AND ANSWERS WITH RATIONALES ALREADY GRADED A+ Counter Triggering Method - Answer-• Output number increases by one at every pulse due to a toggling effect Counter - Answer-• Memory register with special features • A counter is a flip-flop interconnection having an input that enables binary counting. Every time an input is received, the register changes in a regular pattern. Changes are also prearranged by the system Frequency Division/...

What is an Ampere (A, amp, amperage)? - Unit of measurement for flow of electrons (electrical current) Unit of measurement for flow of electrons (electrical current) - Ampere (A, amp, amperage) Amperage in mathematical problems is expressed by what letter? - I How many electrons are in a Coulomb? - 6.28 billion-billion (6.28x10^18) 1 Coulomb per second is equivalent to how many amperes? - 1 What is a Battery? - A device that stores chemical energy and makes the energy available in electri...

Capacitance - The amount of electrical charge that can be stored in a capacitor under a given amount of voltage (pressure); causes the current to lead in applied voltage Effective Value - Value of sine-wave AC needed to produce the same amount of heat as the value of the direct current Inductance - Causes voltage to be produced when it is cut or crossed by lines of magnetic flux; causes current to lag the applied voltage Peak Voltage - Voltage measured from zero to the highest number of vo...
