Flashcard 1

Q: What is a circuit?

A: A circuit is a closed loop that electricity can flow through.

Flashcard 2

Q: What is an open circuit?

A: A path that is broken, so electricity can’t flow.

Flashcard 3

Q: What is a closed circuit?

A: A complete path that lets electricity flow.

Flashcard 4

Q: What is current?

A: Current is the flow of electricity in a circuit.

Flashcard 5

Q: What unit do we use for current?

A: Ampere or Amp (A)

Flashcard 6

Q: What is the symbol for current?

A: I

Flashcard 7

Q: What is voltage?

A: Voltage is the push that makes electricity move.

Flashcard 8

Q: What unit do we use for voltage?

A: Volt (V)

Flashcard 9

Q: What is the symbol for voltage?

A: V

Flashcard 10

Q: What is resistance?

A: Resistance slows down the flow of current.

Flashcard 11

Q: What unit is used for resistance?

A: Ohm (Ω)

Flashcard 12

Q: What does a resistor do?

A: It slows down how much current flows.

Flashcard 13

Q: What is a diode?

A: A diode lets electricity flow in only one direction.

Flashcard 14

Q: What is an LED?

A: A light that turns on when electricity flows through it one way.

Flashcard 15

Q: What does a capacitor do?

A: It stores and releases electrical energy.

Flashcard 16

Q: What unit is used for a capacitor?

A: Farad (F)

Flashcard 17

Q: What is a battery used for in a circuit?

A: It gives the push (voltage) to make electricity flow.

Flashcard 18

Q: What does a switch do?

A: It turns a circuit ON or OFF.

Flashcard 19

Q: What is ground in a circuit?

A: A zero voltage point, used for safety and reference.

Flashcard 20

Q: What is a power supply?

A: A device that gives voltage and current to a circuit.

Flashcard 21

Q: What is a multimeter used for?

A: To measure voltage, current, and resistance.

Flashcard 22

Q: What is a fuse?

A: A safety part that breaks the circuit if too much current flows.

Flashcard 23

Q: What is a circuit breaker?

A: A safety switch that turns off power when there’s a problem.

Flashcard 24

Q: What is a short circuit?

A: When electricity takes the wrong path and skips the full circuit.

Flashcard 25

Q: What’s the difference between AC and DC?

A: AC goes back and forth. DC flows in one direction only.
