Diamond is the most thermally conductive material, with conductivity levels 5 times that of copper, the most commonly used metal in the US. Diamond atoms have a simple carbon backbone, which is an excellent molecular structure for heat transfer.

The current in the wires of a circuit is 60.0 milliAmps. If the voltage impressed across the ends of the circuit were doubled (w

Pavel [41]

Answer:

120 mA

Explanation:

The relationship between voltage, current and resistance in a circuit is given by Ohm's law

$I=\frac{V}{R}$

where

I is the current

V is the voltage

R is the resistance

In this problem, we have an initial current of

I = 60 mA

Then the voltage is doubled:

V' = 2 V

while the resistance is kept the same:

R' = R

So the new current is

$I' = \frac{V'}{R'}=\frac{2V}{R}=2\frac{V}{R}=2 I$

so, the current has doubled. Since I = 60 mA, the new current is

$I' = 2(60 mA)=120 mA$
