Answer:
There are different phases of railroad expansion with the innovations in technology.
Explanation:
Few of the technological innovations are described below that leads in railroad expansion more rapid.
1. Centralized Traffic control (CTC) is introduced in 1960's that is used to control the traffic on railroads using different signal control.
2. In 1990's after computer technology involvement, railway ticket and reservation system is automate and being centralized. That makes the railroad expansion improve.
3. Bullet train technology has been introduced, that makes the railway trains more faster.
4. Electric trains has been introduced to use green energy and reduce the dependency on the fuel to make environment clean and green.
Answer:
In a series connection, the current is the same through each component regardless of any kind of components are used or their values. The voltage drops across each component in the circuit are dependent upon the values of the components used in the circuit. Another way to view a series connection is that the positive end of each component is connected to the negative end of the previous component in a 'one after the other' arrangement. The negative end of each component is also connected to the positive end of the next component.
It is one of which every component is arranged in a series connection. Hence series circuit will have same current at all points of the circuit. The voltage drop across each component in the circuit adds up to sum of voltage source across each component and of an equivalent component value. Breaking of the series circuit will make entire circuit to stop working. Suppose consider the three bulbs are connected in series connection and if even one bulb burns out or broken then all the three bulbs will stop working as well. In series circuit components like current (I) is sum of all the element and Voltage is sum of all the voltage drops and resistance is the sum of individual resistances.

Plagiarism is quite a bad thing because if you plagiarize, you are copying and pasting other people's work and using the work as yours (even though you change the sentence structure/ some words, it is still plagiarizing.) Fair use means un-biasness.
