A power transmission line is hung from metal towers with glass insulators having a resistance of 1.00×109 Ω . What current flows

Hunter-Best [27]

Answer:

The current flows through the insulator is 2 mA.

Explanation:

Given that,

Resistance $R=1.00\times10^{9}\ \Omega$

Voltage = 200 kV

We need to calculate the current

Using ohm's law

$V=IR$

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

Where, I = current

V = voltage

R = resistance

Put the value into the formula

$I=\dfrac{200\times10^{3}}{1.00\times10^{9}}$

$I=0.0002\ A$

$I=2\ mA$

Hence, The current flows through the insulator is 2 mA.

A road that rises 1 ft for every 100 ft traveled

Lana71 [14]

Explanation:

6% grade

=> Rises 6 feet for every 100 feet traveled

This would mean that tanx = 6/100.

=> x = tan^-1(6/100) = 3.4°. (1d.p.)

Hence the road is inclined at an angle of 3.4° above the horizontal.
