- To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
- To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
- To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
- To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)
Q. What is the main function of switch?
The purpose of a switch in a series circuit is to make it easy to open or close the electrical circuit, turning the flow of electricity on or off. A light bulb in a series circuit is used to determine whether or not electricity is flowing.
Q. What are the three functions of switches?
Three basic functins of a switch are Learning, Forwarding and Preventing Layer 2 Loops.
Q. What are the main four functions of switches?
Port Number – The switch port attached to the destination MAC….Switch mainly performs these functions:
- Learning – The switch learns the MAC address of the device on the switch port on which it receives the frame.
- Forwarding – The switch does 2 types of message forwarding:
Q. Why is switching needed?
Switches are used to connect multiple devices on the same network within a building or campus. For example, a switch can connect your computers, printers and servers, creating a network of shared resources. The switch would serve as a controller, allowing the various devices to share information and talk to each other.
Q. Which device is used for switching?
When an electronic switch is on, it is considered closed in a circuit. When the switch is classified as off the switch is open in the circuit. Typically, electronic switches use solid state devices such as transistors, though vacuum tubes can be used as well in high voltage applications.
Q. What are the different switching devices in the starting system?
Motor starters. Disconnectors, load-break switches and switch disconnectors. Fuses.
Q. What are high power switching devices?
Some common power devices are the power MOSFET, power diode, thyristor, and IGBT. The power diode and power MOSFET operate on similar principles to their low-power counterparts, but are able to carry a larger amount of current and are typically able to withstand a larger reverse-bias voltage in the off-state.
