Is a wooden spoon a conductor or insulator?
Wood is an insulator. Think about it; when you put a wooden or plastic spoon in boiling water, does it burn your hand? No. This is because it slows the flow of heat from the water to your hand. I do not suggest trying the same thing with a metal spoon, which is a good conductor.
Why does a metal rod feels colder to touch than a wooden rod at the surrounding temperature?
Metal is an excellent conductor of heat. The moment you grasp the metal rod, the heat of your hand is conducted away rapidly by the dense metal. If feels "chilly". Wood is a poor conductor of heat. It does not conduct away the heat of your hand,and the wooden rod stays comfortably warm in your hand.
Is a foil an insulator or conductor?
Aluminum foil can be use as both insulator and conductor. It can wrap and trap air inside cause thermal insulating effect but in other hand, aluminum itself is a conductor for evenly distribution of heat throughout the food. Aspect of substance fabricated is different from an insulation conduction aspect of a substance.
Is a seashell a conductor or insulator?
conductor
Is a brass paper fastener a conductor or an insulator?
it is a conductor
What does the conductor of a marching band hold in his or her hand?
baton
Could you generate power by hand generator?
yes, because our hand is one of the type of conductor
What does the person usually hold in his hand when he is directing an orchestra?
The conductor of an orchestra holds a baton in his hand.
What does a conductor hold in his hand?
conducting baton
Which law gives the direction of magnetic field due to a current carrying conductor?
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
Is oven glove a good thermal conductor?
No, because if it is then your hand will get burned
What is the principle of motor action?
Motor runs by the principle of Michael Faraday's Electromagnetic Induction. It is defined as "when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field". The direction of rotation is determined by the Right-hand Rule and is "if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand".

What is the Difference between left hand rule and right hand rule?
Fleming's right hand rule shows the direction of induced current flow when a conductor moves in a magnetic field. Fleming's left hand rule shows the direction of the thrust on a conductor carrying a current in a magnetic field.
Is a human being a conductor of heat?
human is not a good conductor because if u can touch the water heater with your hand then the heat can't flow through out your body that's why the human body does not a good conductor.
Which is a better conductor of electricity copper or silicon?
Silicon is only a semiconductor. Copper on the other hand is used to make wires and is an excellent conductor of electricity.
Is a human being good conductor of heat?
human is not a good conductor because if u can touch the water heater with your hand then the heat can't flow through out your body that's why the human body does not a good conductor.
