physics circuits

Question 1

A property of matter that causes it to experience a force when placed in
an electric field. There are two types: positive (+) and negative (-).

Answer 1

Electric Charge

Question 2

The flow of electric charge around a circuit. Measured in amperes (A) using an
ammeter.

Answer 2

current

Question 3

The potential difference between two points in a circuit. It provides the
energy needed to push charges through the circuit. Measured in volts (V).

Answer 3

Voltage (V)

Question 4

A measure of how much a material opposes the flow of current. Measured
in ohms (Ω).

Answer 4

Resistance (R)

Question 5

A complete path through which electric current can flow.

Answer 5

full circuit

Question 6

• A circuit in which components are connected one after another, so there is
  only one path for the current to take.

Answer 6

Series Circuit

Question 7

• A circuit where the components are connected across multiple paths,
  allowing current to flow through different routes.

Answer 7

Parallel Circuit

Question 8

A material that allows electric current to flow through it easily, such as metals
like copper.

Answer 8

Conductor

Question 9

A material that does not allow electric current to flow through it easily, like
rubber, plastic, or wood.

Answer 9

insulator

Question 10

Negatively charged particles that flow through conductors to create an electric
current.

Answer 10

Electrons -

Question 11

The build-up of electric charge on the surface of an object, often caused
by friction between two different materials.

Answer 11

Static Electricity -

Question 12

• A region around a charged object where it exerts a force on other charged
  objects.

Answer 12

Electric Field

Question 13

• The forces of attraction or repulsion between charged objects.

Answer 13

Electrostatic Forces

Question 14

• The force that occurs when two surfaces rub against each other, which can
  transfer electrons and cause static electricity.

Answer 14

Friction

Question 15

• A safety process where excess electric charge is transferred to the
  Earth to prevent electric shocks.

Answer 15

Earth (Grounding)

Question 16

• A device that stores chemical energy and converts it to electrical energy in a circuit.
  One or more cells connected together form a battery.

Answer 16

Cell -

Question 17

• A collection of cells connected together to provide electrical energy.

Answer 17

Battery

Question 18

A device used to measure electric current in a circuit.

Answer 18

Ammeter -

Question 19

• A device used to measure the voltage across components in a circuit.

Answer 19

Voltmeter

Question 20

A device that produces light when electric current passes through it. It converts
electrical energy into light and heat energy.

Answer 20

Lamp -

Question 21

A fault in a circuit where electricity bypasses part of the circuit, often
causing a large current that can be dangerous.

Answer 21

Short Circuit -
