What is the difference between a galvanometer and an ammeter?
A galvanometer is a device used to detect small electric currents, while an ammeter is a device used to measure the strength of electric currents. The main difference is that a galvanometer is more sensitive and used for detecting small currents, while an ammeter is used for measuring larger currents.
Why do currents flow to the right in the northern hemisphere?
In the northern hemisphere, currents are influenced by the Coriolis effect, which causes moving air or water to be deflected to the right. This is due to the rotation of the Earth, which causes an apparent force to the right of the direction of motion in the northern hemisphere. As a result, currents tend to flow in a clockwise direction in the northern hemisphere.
What is the significance of the liquid-filled bulbs in a Galileo thermometer and how do they contribute to its functionality?
The liquid-filled bulbs in a Galileo thermometer are different densities of liquid that rise or fall with temperature changes. This causes the bulbs to float or sink, indicating the temperature. The bulbs help the thermometer accurately measure temperature by showing the temperature through the movement of the bulbs.
What is the name for the potential difference that causes current to flow?
The name for the potential difference that causes current to flow is voltage.
What happens to the voltage as more bulbs are added in series?
The voltage in a series circuit is divided among the bulbs, so as more bulbs are added in series, each bulb receives less voltage. This causes the brightness of each bulb to decrease compared to when fewer bulbs are present.
How does the uneven heating in the ocean cause convection currents?
it causes the difference in density, denser water flows to the less dense parts
What causes the global convection current between the equator and the polls?
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.
What are causes of the ocean currents?
The two causes of ocean currents are wind and the rotation of the earth(etc) The wind blows which makes the currents in the water and the rotation of the earth(gravity) makes currents in the ocean currents. Luaye Sharawy
What causes the global air convection current between the equator and the polls?
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.
What are the causes of currents?
its caused by the moon
What causes high and low currents?
In electricity? High voltage ,high currents. Low voltage, low currents.
What causes density currents?
Currents in the coastal water masses
Describe the similarities and differences between gyres and currents?
A difference between gyres and currents is that currents are formed by the wind, but gyres are formed by currents.
What causes surface currents to move?
Randomism .
What causes ocean currents and why is it important?
waves
What causes your plates to move?
convection currents!
How do deep ocean currents occur?
It is from differing temperatures of air above it that causes currents to flow in the water.
