# What is a basic circuit?

A circuit is an unbroken loop of conductive material that allows electrons to flow through continuously without beginning or end. If a circuit is “broken,” that means its conductive elements no longer form a complete path, and continuous electron flow cannot occur in it.

### What is a basic electric circuit composed of?

An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow.
• #### What is simple electric circuit?

A circuit is a closed path that electrons flow along. A simple electric circuit contains a power source (battery), wires, and a resistor (light bulb). In a circuit, electrons flow from the battery, through the wires, and into the light bulb.
• #### What are the three basic parts of an electrical circuit?

The 3 main parts of an electric circuit and their functions are: Power source - Either electrical or battery, provides the power to the load. Load - The device using the electricity such as a computer, light bulb, power saw, etc.
• #### What is a fuse and a circuit breaker?

A fuse is made up of a piece of metal that melts when overheated; a circuit breaker has an internal switch mechanism that is tripped by an unsafe surge of electricity. Fuses tend to be quicker to interrupt the flow of power, but must be replaced after they melt, while circuit breakers can usually simply be reset.

### How does a simple electric circuit work?

An electric circuit is like a pathway made of wires that electrons can flow through. A battery or other power source gives the force (voltage) that makes the electrons move. When the electrons get to a device like a light bulb, your computer, or a refrigerator, they give it the power to make it work.
• #### How does a circuit breaker?

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.
• #### What is the device called that measures electric current?

An ammeter is a current tester that measures electrical current in automotive applications. Sometimes called a clamp-on meter, a clamp meter measures electrical current without touching or interrupting the circuit. Current clamps and current probes are attachments for electrical testing devices that measure current.
• #### What is an ammeter in a circuit?

An ammeter (from Ampere Meter) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters.

### What does a simple electrical circuit consist of?

A circuit is the path that an electric current travels on, and a simple circuit contains three components necessary to have a functioning electric circuit, namely, a source of voltage, a conductive path, and a resistor. Circuits are driven by flows.
• #### What does a simple electrical circuit consist of?

• #### What is the definition of a closed circuit?

closed circuit. An electric circuit through which current can flow in an uninterrupted path. Compare open circuit. A television system in which the signal is usually sent by cable to a limited number of receivers.
• #### How does a battery produce electricity?

The electrolyte is a chemical medium that allows the flow of electrical charge between the cathode and anode. When a device is connected to a battery — a light bulb or an electric circuit — chemical reactions occur on the electrodes that create a flow of electrical energy to the device.
