Q. Data transmission in Bus Topology ?
Bus Topology:This topology shares a single path or link way among all users. This common single path way is called bus. In this topology, link serves as a high way for all data signals and users connect on to the bus at their node location. In bus configurations, network control isn't centralized to a particular node. Here control is distributed among all nodes connected to the LAN. Data transmission on a bus network is generally in the form of small packets comprising user addresses and data. When one user/node desires to transmit data to another station, it monitors bus to determine if it's currently being used. If no other nodes/users are communicating over the network, monitoring node/user can start to transmit its data. Every node should monitor all transmission on the network and determine which are intended for them.
If a current of 10A flows for four minutes, find the quantity of electricity transferred. Quantity of electricity, Q=It coulombs. I =10A and t = 4 × 60 = 240s. Hence Q =
Referring to Figure, let boxes 2, 3, and 5 consist of a 0.2-H inductor, a 5- resistor, and a 0.1-F capacitor, respectively. Given A = 5, and v 1 = 10 sin 10t, i 2 = 5 sin 10t ,
In the circuit shown below, the capacitor initially has a voltage across it 4 Volts (at t = 0). a. Write down the expression for V C (t) when the switch is closed. b. Writ
Q. A 100-kVA, 2300:230-V, 60-Hz, single-phase transformer has the following parameters: R 1 = 0.30 , R 2 = 0.003 , RC 1 = 4.5k, X 1 = 0.65 , X 2 = 0.0065 , and Xm 1 = 1.
#The requirement is as follows- There is a signal which is in the range of 0 to 5Hz. This signal frequency composition is to determined. The resolution of the determination is 1Hz.
