Ison Technologies Interview Questions and Answers

AC and DC currents are two types of electrical currents. AC current periodically changes direction, while DC current flows in one direction.

• AC current stands for Alternating Current and periodically changes direction.

• DC current stands for Direct Current and flows in one direction.

• AC current is commonly used in household electrical systems.

• DC current is used in batteries and electronic devices.

• Examples of AC current sources include power grids and generators.

• Examples of DC cur...read more

Series connection is a method of connecting components in an electrical circuit where the current flows through each component in sequence.

• In series connection, the total resistance is the sum of individual resistances.

• The current remains the same throughout the circuit.

• Voltage is divided among the components based on their resistance.

• Examples include connecting multiple light bulbs in a series or connecting batteries in series to increase voltage.

Types of wiring include electrical, telecommunications, and network wiring.

• Electrical wiring is used for power distribution in buildings and homes.

• Telecommunications wiring is used for telephone and internet connections.

• Network wiring is used for data transmission in computer networks.

• Other types of wiring include audio, video, and security system wiring.

Electromechanical refers to the integration of electrical and mechanical components in a system or device.

• Electromechanical systems combine electrical and mechanical elements to perform a specific function.

• Examples include electric motors, generators, robotics, and automated machinery.

• These systems often involve the conversion of electrical energy into mechanical motion or vice versa.

• Electromechanical engineers design, develop, and maintain such systems.

• They work with compone...read more

A two-way switch is connected by using two switches to control a single light or electrical device from two different locations.

• Two switches are used to control a single light or electrical device from two different locations

• The switches are connected with a three-core and earth cable

• One switch is connected to the live wire and the other switch is connected to the switched live wire

• The earth wire is connected to the metal switch box and the metal faceplate of the switch
