Electricity Flashcards
What is electricity?
Electricity is the presence and flow of electric charge.
True or False: In a series circuit, the current is the same through all components.
True
What is a parallel circuit?
A parallel circuit is a circuit where the components are connected across common points, providing multiple pathways for current.
Fill in the blank: In a series circuit, the total voltage is equal to the _____ of the individual voltages.
sum
What is the symbol for a resistor in a circuit diagram?
The symbol for a resistor is a zigzag line.
Multiple choice: Which of the following components is typically used to store electrical energy? A) Resistor B) Capacitor C) Inductor
B) Capacitor
What happens to the total resistance in a series circuit if more resistors are added?
The total resistance increases.
True or False: In a parallel circuit, if one component fails, the rest of the components will also stop working.
False
What is the unit of electric current?
The unit of electric current is the Ampere (A).
Fill in the blank: The _____ of a circuit is the path through which electricity flows.
circuit
Multiple choice: What is the symbol for a battery? A) A straight line B) A long line next to a short line C) A circle
B) A long line next to a short line
What is Ohm’s Law?
Ohm’s Law states that Voltage (V) = Current (I) x Resistance (R).
True or False: In a parallel circuit, the voltage across each component is the same.
True
What does a voltmeter measure?
A voltmeter measures the voltage across two points in a circuit.
Fill in the blank: The _____ is a device that limits the flow of electric current in a circuit.
resistor
