What is the difference between potential difference and current?
**Current vs potential difference: **The current is a flow of charge. Current is measured through a component. Potential difference is the energy used between two points in a circuit, therefore it is measured between two points either side of a component.
Which instrument used to measure?
List of measuring devices
| Instrument | Quantity measured |
|---|---|
| micrometer | small distances |
| multimeter | electrical potential, resistance, and current |
| nephoscope | to measure the speed and direction of clouds |
| nephelometer | particle in a liquid |
What is a Fathometer used to measure?
Fathometer – Used to measure the depth of the ocean. Galvanometer – Used to measure electric current.
Which instrument is used to measure the depth of the sea?
Depth finder, also called echo sounder, device used on ships to determine the depth of water by measuring the time it takes a sound (sonic pulse) produced just below the water surface to return, or echo, from the bottom of the body of water.
What is used in measuring water?

What is depth of ocean?
That’s 1.7 miles down! The average depth of the ocean is about 12,100 feet . The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.
How do you measure bathymetry?
Today, echo sounders are used to make bathymetric measurements. An echo sounder sends out a sound pulse from a ship’s hull, or bottom, to the ocean floor. The sound wave bounces back to the ship. The time it takes for the pulse to leave and return to the ship determines the topography of the seafloor.
How do you read a bathymetry map?
These maps use color to indicate water depth. On most bathymetric images of the ocean, colors on the “warm” end of the spectrum – red, orange, and yellow – represent shallower water. As the water deepens, the colors shift through green, blue, and finally into violet. Dry land is usually shown in white.
What is bathymetry plan?
A bathymetric chart is a type of isarithmic map that depicts the submerged topography and physiographic features of ocean and sea bottoms. Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
