Answer:

Galvanometer

Explanation:

The device used to detect and measure current and voltage in a circuit is known as a galvanometer. It is based on the principle that a current carrying coil rotates which is suspended in a magnetic field.

Torque acts when a current carrying coil is kept in a magnetic field. It makes the needle of the galvanometer to deflect. The galvanometer is used as ammeter when a low resistance is connected in parallel and as voltmeter when high resistance is connected in series.

notka56 [123]

Explanation:

A metal such as copper is a conductor because it provides a pathway for electric charges to move easily. A material such as rubber is an insulator because it resists the flow of electric charges. A material that partially conducts electric current is a semiconductor. These materials include group 3 and group 5 elements.

does it require more energy to brew 12 cups with the coffee-maker or reheat 12 cups of coffee in a microwave?

Leni [432]

It would take more energy to reheat 12 cups because only 1 or 2 cups can fit in a microwave rather an than brewing 12 cups in a coffee pot.
