Actual Qs and Ans - Expert-Verified Explanation -Guaranteed passing score -100 Questions and Answers
-Format: Multiple-choice / Flashcard
Question 1: Electrical Power
Answer:
Electronics Information: The amount of energy delivered to and used by an electric circuit.
Power: Watts.
Question 2: Electromagnet
Answer:
Electronics Information: When a current is passed through a wire coiled around a ferrous material, the result is known as this.
Question 3: Magnetic Effect
Answer:
When a wire is introduced into a magnetic field, electricity flows through the wire and creates a magnetic field that repels a magnet. This effect is used to create energy through Electromagnetic Induction. If the wire is wrapped around an iron core and a current is sent through the wire, the iron become magnetized.
Question 4: Inductor (symbol)
Answer:
Electronics Information: It is the symbol seen here.
Question 5: current flowing through a wire the 3 influences
Answer:
the amount of voltage, measured in volts.the resistance to the current, measured in ohms.the amount of current, measured in amps.
Question 6: open
Answer:
switch is off, set to a position were there is an opening, a literal open space in the circuit were current cannot flow,
Question 7: Inductance
Answer:
Electronics Information: The circuit property that opposes any change in current.
Question 8: Electricity
Answer:
Electronics Information: The concept of this is defined as the flow of electrons along a conductor
Question 9: Amperes (A)
Answer:
represents the strength of a current
Question 10: Fuse
Answer:
Electronics Information: The symbol of this, seen here.
It is also a thin wire that will blow or melt if the current flowing through it exceeds a particular value.
Question 11: Inversely Proportional
Answer:
Electronics Information: As resistance in a conductor increases, current flow decreases, meaning that current and resistance are related this way.
Question 12: conductors
Answer:
conductors (copper and water) allows the electrons to move freely.
Question 13: Semiconductor
Answer:
an object that conducts electricity poorly at low temperatures, that control the flow of electricity in a circuit. this electrical device can amplify a signal.
Question 14: Ohm's Law
Answer:
the current in a circuit equals the voltage and inversely proportional to the circuit resistance.
Question 15: Magnetic fields depends on several factors
Answer:
Number of turns: if you increase the number of turns, you increase the field strength.
Closeness of the turns: the closer the turns, the stronger the field.
Amount of current: if you increase current, you increase field strength.
Material in the core:most coils are classified as either air or soft iron.
Question 16: air coils
Answer:
are usually wrapped around a piece of card board.
Question 17: Parallel circuits
Answer:
Electronics Information: An electrical circuit where the voltage is the same throughout the circuit, while current flow varies; with this arrangement, each load is wired in a separate path. If any one of these paths were to break or gap, current flow would still continue through the other paths, so there would still remain a closed circuit.
Question 18: Circuit Breaker
Answer:
Electronics Information: This device serves the same function as a fuse, but can be used multiple times.A device that automatically interrupts the electrical current, is an example of opening a circuit to control the current. when the circuit breaker trips, the electrical device can no longer operate.
Question 19: Battery
Answer:
It's the symbol seen here.
Question 20: Watt
Answer:
a watt measures power, the rate at which electrical energy is consumers or transformed into another type of energy, such as light or heat.
Question 21: Volts
Answer:
volts measure the difference of potential between two points. Voltage.
Question 22: Ferrous (iron) core
Answer:
Electronics Information: The magnetic field formed by a current-carrying wire can be strengthened by winding the wire into a coil around this kind of core.
Question 23: physiological effect
Answer:
Current produces this effect when it passes through your bicep (or any other muscle) and causes the muscle to contract. This effect is used in medicine.
Question 24: Capacitance
Answer:
Electronics Information: The ability of the capacitator to store charge, represented by the symbol C, and its unit of measurement is the farad.
Question 25: Negative side (of a battery)
Answer:
Electronics Information: This side of a battery has a huge excess of electrons and pushes them to the other side.
