The East River is a tidal strait, not a real river, which connects on both ends to the Atlantic Ocean. As such, East River's tidal currents change the direction usually four times a day, flowing north and then turning around and going south. There are days however when the directions will be changed only three times in a 24 hour period. The tide reversal times change with the position of the moon and the sun, so there are no fixed times for the direction changes.

Of course. If you take the batteries out of a flashlight and put them back in pointingthe other way, the current goes through the bulb in the opposite direction.It's so easy to reverse the flow of electric current that . . .-- the current coming out of a household electric socket reverses 120 times every second,-- the current in the antenna of your FM radio reverses roughly 200 million times every second-- the current in the antenna of your cellphone reverses almost 2 billion times every second,-- the current in the magnetron that makes the microwaves that heat your leftover meat loafreverses 4.9 billion times every second.

Although DC current can vary in voltage and current over time, it does not reverse polarity, which in AC occurs some distinct number of times per second (hertz) which is the frequency.
The Huang River affects the people that lived near it because over time loess builds up in the river it forming dams, so that caused the river to change its course many times. But when the river suddenly changes course, farms and towns are destroyed. And the Huang river also has many horrible floods. So in a result they call the Huang river "the River of Sorrow".
Dyardanes was the name originally given to the Brahmaputra River in Hindi. In early times the river had a different course, but some of the water still flows through Mymensingh and Jamalpur.
Electricity and water are often compared to help explain how electricity works. Voltage is like the speed of water in a river, and electrical current is like the amount of water in the river. Resistance can be compared to the physical width of the river. Power is voltage times current, or the speed of the water times the amount of water. Electricity is usually most dangerous when it is available at high power - similar to a huge, fast moving river.
I think you mean CONTEMPORARY. This means up to date or modern. Another term for that would be cutting edge. The opposite would be old fashioned or out of date. You might also say behind the times.
Outside the battery, it is negative to positive and inside the battery it is positive to negative.
In an alternating current (AC) circuit, the electric charge periodically reverses direction at a certain frequency. This is in contrast to a direct current (DC) circuit, in which charge flows in one direction only.
it is the indus river
In the King James version the word - river - appears 175 times the word - river's - appears 4 times the word - rivers - appears 77 times
