A schematic is a representation, typically found in the form of a diagram, of the elements of a system – using abstract, graphic symbols as opposed to realistic pictures. What do you know about schematics? Let’s take a look.

• 1.

### Identify this schematic

Explanation
This schematic is a representation of a relay, specifically an electrical relay. A relay is an electrically operated switch that uses an electromagnet to control the flow of current in a circuit. It is commonly used in various electrical and electronic systems to control high-power devices with low-power signals. The schematic shows the basic components and connections of a relay, including the coil, contacts, and terminals.

### Identify this schematic

Explanation
This schematic represents various elements commonly found in electrical or electronic circuit diagrams. The term "node" refers to a point where two or more components or wires are connected. "Wires crossed" indicates that two wires are intersecting or crossing each other. "Connected wires" implies that two or more wires are linked or joined together. Lastly, "connected tracks" suggests that two or more conductive paths or traces on a circuit board are connected.

### Identify this schematic

Explanation
The given answer "resistor" correctly identifies the schematic shown in the question. A resistor is an electronic component that is used to resist the flow of electric current in a circuit. It is represented by a zigzag line in schematic diagrams, which matches the image provided.

• 4.

### Identify this schematic

Explanation
This schematic is identifying the concept of voltage, specifically positive voltage and positive voltage supply. Voltage refers to the electric potential difference between two points in a circuit. Positive voltage indicates that the potential at a certain point is higher than the reference point. Positive voltage supply refers to the source of positive voltage in a circuit, typically provided by a power source such as a battery or power supply.

### Identify this schematic

Explanation
The given schematic is a capacitor. A capacitor is an electronic component that stores and releases electrical energy. It consists of two conductive plates separated by an insulating material called a dielectric. When a voltage is applied across the plates, the capacitor charges and stores electrical energy. It can then release this stored energy when needed. Capacitors are commonly used in electronic circuits for various purposes, such as filtering, smoothing, and energy storage.

• 6.

### Identify this schematic

Explanation
The given answer "ground" is the identification of the schematic. In electronic circuits, ground is a reference point that serves as a common return path for electric current. It is typically represented by the symbol "GND" or a horizontal line with three downward-pointing arrows. Ground is used to provide stability, safety, and a common voltage reference for the circuit.

### Identify this schematic

Explanation
The given schematic is known as a potentiometer, also referred to as POT or a variable resistor. A potentiometer is an adjustable electrical component that is commonly used to control the flow of electric current in a circuit. It consists of a resistive track and a sliding contact, which can be moved along the track to vary the resistance. This allows for precise control of the current or voltage in a circuit, making it a versatile component in various electronic applications.

### Identify this schematic

Explanation
The given schematic represents a transistor. A transistor is a semiconductor device that can amplify or switch electronic signals and electrical power. It is composed of three layers of semiconductor material, namely the emitter, base, and collector. The schematic symbol of a transistor consists of two intersecting lines with an arrow indicating the direction of current flow. Transistors are widely used in electronic devices such as amplifiers, radios, and computers.

Rate this question:

• 9.

### Identify this schematic

Explanation
The schematic shown in the question represents unconnected wires and unconnected tracks. This means that the wires and tracks in the schematic are not properly connected or linked together. This can lead to a disruption in the flow of electrical signals and can cause issues in the circuit's functionality. It is important to ensure that all wires and tracks are properly connected in order to maintain a functional and efficient circuit.

Rate this question:

• 10.

### Identify this schematic

Explanation
The given schematic is a switch. A switch is an electrical component that can make or break an electrical circuit. It is used to control the flow of electricity by opening or closing the circuit. When the switch is in the "on" position, the circuit is closed and electricity can flow through it. When the switch is in the "off" position, the circuit is open and electricity cannot flow. Switches are commonly used in various electrical systems and devices to control the power supply.

• 11.

### Identify this schematic

Explanation
The schematic being identified in this question is a photocell or a light dependent resistor. A photocell is a type of resistor whose resistance decreases with increasing light intensity. It is commonly used in light-sensing applications, such as automatic street lights, solar panels, and cameras. The term "light dependent resistor" is another name for a photocell, as it accurately describes its function of changing resistance based on light levels.

### Identify this schematic

Explanation
The given schematic is for an LED, which stands for Light Emitting Diode. An LED is a semiconductor device that emits light when an electric current passes through it. It is commonly used in various electronic devices and lighting applications due to its energy efficiency and long lifespan. The schematic represents the basic structure of an LED, consisting of a forward-biased p-n junction that allows the flow of electrons and the emission of light.
