• Transformers are used to increase or decrease the voltage levels in electrical power transmission and distribution systems.

• They consist of two or more coils of wire, known as windings, which are wound around a core made of magnetic material.

• The primary winding is connected to the input v...read more

Current in a motor can be found using an ammeter.

• Connect the ammeter in series with the motor

• Turn on the motor and measure the current

• Current can be found using the formula I = V/R

• Use a clamp meter to measure current without breaking the circuit

MPLS is a protocol used for efficient packet forwarding. It uses labels to identify paths instead of IP addresses.

• MPLS stands for Multiprotocol Label Switching

• Labels are assigned to packets at the ingress router

• Labels are used to identify the path a packet should take through the network

• Labels are swapped at each MPLS router along the path

• The last MPLS router removes the label and forwards the packet based on the IP ad...read more

Route reflector is a BGP feature that allows a router to advertise routes to its clients without requiring full mesh connectivity.

• Route reflector reduces the number of iBGP peerings required in a network.

• It helps in scaling the network by reducing the number of updates and processing required.

• Route reflector can be configured in a hierarchical manner to further reduce the number of iBGP peerings.

• It is commonly used in ...read more
