volt is a measure of: Electromotive Force, or , Electrical Potential
What is the equation to solve for power (P)? P = V(I), power = volt x current
Define Coloumbs Law The SI unit of a electrical charge, equal to the quantity of electricity conveyed in
one second by a current of one ampere
What is Ohm's law equation? voltage = current x resistance, v=i(r)
(I) or (a) sometimes (e) in ohms law is known as ? An Ampere (amps)
What is the base unit of charge? A Coloumb
In conventional Current Flow; What direction does From positive to negative
electrons flow?
In real life what direction do electrons actually flow? From negative to positive (not used for electric engineering)
The flow of electric charge that regularly reverse in Alternating Current ( A/C)
polarity is said to be ?
______ ______ is the one directional flow of an electric Direct Current ( D/C)
charge.
In a RCL circuit the phase difference between Voltage & Less than 90 degrees
Current is said to be ?
Solve for V; if the current is set to 2a, with a resistance of 30v
15 ohms. What is the Voltage?
Solve for i; in a series circuit the voltage is 20v and there 4 amps
are two resistors @ 4ohms and 1ohms. What is the
current value?
Solve for R; voltage is at 50v with a current of 25 amps . 2 ohms
What is the value of the resistor ?
When an applied frequency is increased in a circuit Inductive reactance increases
containing both and inductor and a capacitor ; what
happens to inductive reactance?
A Capacitor opposes any change in the _________ of a Voltage (V)
defined circuit.
, AT&T TKT II
Inductance opposes a change in the? Current (i)
Three Resistors connected in parallel with values of 15, 3.06 ohms,
10 and 6 ohms . What is the total resistance ?
to solve for total resistance you must get the inverse value of each resistor and
then get the inverse value of that number.
So 1/15 + 1/10 + 1/6 = .326 —> 1/.326= 3.06
