Why do wires usually warm up when an electric current is in them?
Wires warm up when an electric current flows through them due to the resistance in the wire. The resistance converts some of the electrical energy into heat, causing the wire to warm up. This is described by Ohm's Law, which states that the heat generated is directly proportional to the resistance and the square of the current flowing through the wire.
What form of energy is changed when you warm up under an electric blanket?
Electrical energy is converted to thermal energy when you warm up under an electric blanket. The electric current flowing through the blanket's heating elements generates heat, which warms up the blanket and then transfers heat to your body when you lie underneath it.
Name the warm ocean current flowing along the east coast of Africa?
The Mozambique current
What is the name of the most important warm current flowing along the Atlantic coast of north America?
The Gulf Stream
Why do electric devices feel warm after they have been on for a period of time?
Electrical devices utilize electricity to perform work. Some energy will be dissipated in heat produced by electrical current flowing through the various conductive surfaces within the device.
What is a north Atlantic current?
The North Atlantic Current is a vast, slow moving warm current. It is created from the Gulf Stream and the Labrador Current joining at southern Greenland, which creates the widening and slowing of the Gulf Stream. The North Atlantic Current splits near western Europe, one part creating the warm Norway Current flowing northward along the coast of Norway and the other creating the cold Canary Current deflecting southward, eventually warming and rejoining the North Equatorial Current.
What is the Difference between drift and ocean current?
ocean currents can be warm or cold.they are streams of water flowing constantlyon the ocean surface.
What is the shape of the graph between volt and electric charge where Volt is the potential difference between the ends of an ohmic resisitor and electric charge is the current flowing through it?
-- If one axis of your graph represents the current flowing through the resistor, then label it "Current", not "Electric charge". There's a big difference between charge and current. -- Ideally, the current through an ohmic resistor is a linear function of the voltage across its ends, namely a direct proportion with the resistance being the constant of proportionality. -- Ideally, the graph is a straight line, with slope equal to the resistance in ohms, and y-intercept of zero. -- In reality, the resistor dissipates energy at the rate of (voltage) x (current) watts. It must warm up as a result, and the change in its temperature always has some effect on its ohmic resistance.
Name an ocean current that transports warm water away from tropical oceans?
The Gulf Stream is a warm ocean current that transports water away from tropical oceans, flowing from the Gulf of Mexico into the North Atlantic Ocean.
Does an electromagnet need to warm up?
No, an electromagnet does not need to warm up. It can generate a magnetic field instantly when an electric current flows through its coils.
What is the definition for golf stream?
warm ocean current flowing from the gulf of mexico north along the coast of the united states and then east to europe
An oceanographer notes a whirlpool of warm water in the middle of the cold Sargasso Sea How is this possible?
A countercurrent is flowing in the opposite direction of the wind-related current.
