GUIDE COMPLETE QUESTIONS AND
CORRECT ANSWERS
●● What is the equation to solve for power (P)?
Answer: P = V(I), power = volt x current
●● Define Coloumbs Law
Answer: 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?
Answer: voltage = current x resistance, v=i(r)
●● (I) or (a) sometimes (e) in ohms law is known as ?
Answer: An Ampere (amps)
●● What is the base unit of charge?
Answer: A Coloumb
●● In conventional Current Flow; What direction does electrons flow?
Answer: From positive to negative
,●● In real life what direction do electrons actually flow?
Answer: From negative to positive (not used for electric engineering)
●● The flow of electric charge that regularly reverse in polarity is said to
be ?
Answer: Alternating Current ( A/C)
●● ______ ______ is the one directional flow of an electric charge.
Answer: Direct Current ( D/C)
●● In a RCL circuit the phase difference between Voltage & Current is
said to be ?
Answer: Less than 90 degrees
●● Solve for V; if the current is set to 2a, with a resistance of 15 ohms.
What is the Voltage?
Answer: 30v
●● Solve for i; in a series circuit the voltage is 20v and there are two
resistors @ 4ohms and 1ohms. What is the current value?
Answer: 4 amps
, ●● Solve for R; voltage is at 50v with a current of 25 amps . What is the
value of the resistor ?
Answer: 2 ohms
●● When an applied frequency is increased in a circuit containing both
and inductor and a capacitor ; what happens to inductive reactance?
Answer: Inductive reactance increases
●● A Capacitor opposes any change in the _________ of a defined
circuit.
Answer: Voltage (V)
●● Inductance opposes a change in the?
Answer: Current (i)
●● Three Resistors connected in parallel with values of 15, 10 and 6
ohms . What is the total resistance ?
Answer: 3.06 ohms,
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
