Maiking Circuits Flashcards
What is a circuit?
A circuit is a closed loop that allows electric current to flow.
True or False: A circuit must have a power source.
True
Fill in the blank: The basic components of a circuit include a power source, ______, and a load.
conductors
What is the function of a resistor in a circuit?
A resistor limits the flow of electric current.
Multiple Choice: Which component stores electrical energy in a circuit? A) Resistor B) Capacitor C) Inductor
B) Capacitor
What is Ohm’s Law?
Ohm’s Law states that V = I * R, where V is voltage, I is current, and R is resistance.
True or False: Series circuits have multiple paths for current to flow.
False
What happens to the total resistance in a series circuit?
The total resistance increases as resistors are added.
Fill in the blank: In a parallel circuit, the voltage across each component is ______.
the same
Multiple Choice: What is the unit of electrical current? A) Volt B) Ampere C) Ohm
B) Ampere
What is the purpose of a switch in a circuit?
A switch controls the flow of current by opening or closing the circuit.
True or False: A short circuit occurs when there is an unintended low-resistance connection in a circuit.
True
What is a breadboard used for?
A breadboard is used for prototyping and testing electronic circuits without soldering.
Fill in the blank: The ______ is the part of the circuit that converts electrical energy into another form of energy.
load
Multiple Choice: Which of the following is a passive component? A) Transistor B) Diode C) Resistor
C) Resistor
What is the effect of increasing resistance in a circuit?
Increasing resistance decreases the current flow, assuming voltage remains constant.
True or False: Capacitors can only store energy in a DC circuit.
False
What is the purpose of a diode in a circuit?
A diode allows current to flow in one direction only.
Fill in the blank: The ______ is the total amount of electric charge that flows through a circuit over time.
current
Multiple Choice: Which component can amplify current in a circuit? A) Resistor B) Capacitor C) Transistor
C) Transistor
What is the role of an inductor in a circuit?
An inductor stores energy in a magnetic field when current flows through it.
True or False: A multimeter can measure voltage, current, and resistance.
True
What is the relationship between power, voltage, and current?
Power (P) is the product of voltage (V) and current (I), expressed as P = V * I.
Fill in the blank: A ______ circuit is one where components are connected end-to-end.
series
Multiple Choice: Which device is used to protect a circuit from overload? A) Fuse B) Capacitor C) Diode
A) Fuse
What safety precautions should be taken when working with circuits?
Always disconnect power before working on a circuit, and use insulated tools.
