Questions & Answers (GRADED A)
Electrical power can be calculated with the following formula: P = I x V
What does the letter I represent in this formula?
A. watts
B. voltage
C. current
D. impedance - ANSWER -The correct answer is (C) current. P represents power,
which is measured in watts. I represents current, which is measured in amperes. V
represents voltage which is measured in volts.
What is the load in this basic circuit model?
See Picture
A. A
B. B
C. C
D. D - ANSWER -The correct answer is (C) C. In a basic circuit model, there is a
voltage source (pictured here as a battery at points A and B), a load, and conductors.
The conductors are drawn using the lines and arrows. The load in this model is the light
bulb pictured at point C. Examples of loads are light bulbs, resistors and motors.
Three amps equals how many milliamps?
A. 0.003
B. 30
C. 300
D. 3,000 - ANSWER -The correct answer is (D) 3,000.. A milliamp is one thousandth of
an amp. So every amp equals 1,000 milliamps:
3 x 1,000 = 3,000.
What type of electrical circuit is depicted above?
See Picture
A. simple circuit
B. series circuit
C. parallel circuit
, D. series-parallel circuit - ANSWER -The correct answer is (D). A series-parallel circuit
has some loads wired in series and some loads wired in parallel. The loads in this circuit
are R1, R2, and R3. R1 is wired in series while R2 and R3 are wired in parallel.
What device would you use to measure electrical resistance in a circuit.
A. ohmmeter
B. voltmeter
C. ammeter
D. electricity meter - ANSWER -The correct answer is (A) ohmmeter. Electrical
resistance is measured in ohms, and can be measured with an ohmmeter.
Which of the following is NOT a type of resistor?
A. potentiometer
B. dielectric
C. rheostat
D. variable - ANSWER -The correct answer is (B). A potentiometer is a three terminal
resistor with a sliding contact. A rheostat is a two terminal variable resistor. A variable
resistor is any resistor that allows you to change the amount of resistance.
Potentiometers and rheostats are both types of variable resistors.
Which of these electrical devices can be used to store an electric charge?
A. Semiconductor
B. Diode
C. Capacitor
D. Transistor - ANSWER -Capacitors consist of one or more pairs of metal conducting
plates that are separated by an insulator. The insulator is called the dielectric. An
electric charge builds up when a voltage is applied across the plates, which creates an
electric field.
What does this symbol refer to?
See Picture
A. piezo transducer
B. relay switch
