Volt is an indicator of: ANSWER Electrical potential, also known as
electromotive force
Which equation needs to be solved for power (P)? P = V(I), power = volt x
current is the ANSWER .
ANSWER : Describe Coloumb's Law The amount of electricity carried by a
current of one ampere in a second is the SI unit of an electrical charge.
What is the equation for Ohm's law? ANSWER voltage = resistance x current,
v=i(r)
What is (I) or (a) in Ohm's law sometimes called (e)? An Ampere (amps) is the
ANSWER .
What is the charge's basic unit? - ANSWER A Coloumb
Which way do electrons move in a normal current flow? ANSWER : From
favorable to unfavorable
What is the actual direction of electron movement in the real world? -
ANSWER (not used for electric engineering): From negative to positive
What is the term for the regular polarity reversal of an electric charge flow?
ANSWER : A/C Alternating Current _The one-way flow of an electric charge is
_____ ______. ANSWER : D/C (Direct Current)
The phase difference between voltage and current in an RCL circuit is defined
as? ANSWER : Under 90 degrees
If the current is set at 2 a and the resistance is 15 ohms, find V. What is the
voltage? ANSWER 30v
Determine i. In a series circuit, there are two resistors at 4 and 1 ohms, and the
voltage is 20 volts. What is the value right now? ANSWER : 4 amps
, Determine R; the voltage is 50 volts and the current is 25 amps. What is the
resistor's value? ANSWER : Two ohms
What happens to inductive reactance in a circuit with a capacitor and an
inductor when the applied frequency is raised? ANSWER : An increase in
inductive reactance
Any alteration to a designated circuit's ___ is opposed by a capacitor. The
voltage (V) in response
A change in the inductance is opposed by the? - Current ANSWER (i)
Three parallel-connected resistors with resistances of 15, 10, and 6 ohms. How
much resistance is there overall? ANSWER 3.06 Ohms
You must first determine the inverse value of each resistor before determining
the inverse value of that number in order to solve for total resistance.
Thus, 1/.326 = 3.06 —> 1/15 + 1/10 + 1/6 =.326
What is meant by AC voltage across a pure inductance? ANSWER : 90 degrees
ahead of the current
To what extent is current flow opposed? ANSWER : An AC circuit's
impedance
Which three elements determine a conductor's direct current resistance?
ANSWER Temperature, thickness, and length
Does every branch in a parallel circuit have the same voltage (V)? Is it true or
not? - ACCEPTABLE
AC to DC is converted by a _________ ANSWER Rectifier.
Which three techniques are used to measure a signal? ANSWER Pulse per
millisecond, frequency, and percentage (duty cycle)
The entire amount of current in an open circuit is ___amps. - REPLY 0 amps,
Is it true that a closed circuit and a shorted circuit are the same thing?
ANSWER Untrue
One definition of a short circuit is: ANSWER A malfunction in the intended
