John recently purchased a High Definition plasma television and needed to have it installed. The installers told John that for t

he best picture quality he should use cables with an all-copper core, rubber insulation, and 24k gold contacts. The electrical signal travels down the copper portion of the cable while the rubber insulates the cable from a loss of electrical current and heat. Which physical property explains the difference in ability of copper and rubber to transmit electricity?

Ductility - a materials ability to stretch, ie if you pull it apart does it stretch to a wire.

density - ratio of volume to mass

conductivity - materials ability to conduct a current.

hopefully with these definitions you can figure out the answer.

Calculate Rations. A transformer has ten turns of wire on the input side and 50 turns of wire on the output side. if the input v
Illusion [34]

Answer:

Output voltage = 600 V

Explanation:

Using the transformer equation which simply states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.

Number of input turns/Number of output turns = Voltage of input/voltage of output

10/50 = 120V/voltage of output

Voltage of output = 120 V/0.2

Voltage of output = 600 V
