0. A 1700-W machine operates at 120 V. What i

kap26 [50]

Option D

The resistance in machine is 8.5 ohms

Solution:

Given that,

Power = 1700 W

Voltage = 120 V

We have to find the resistance in machine

The formula used is:

$P = \frac{V^2}{R}$

Where,

"P" is the electric power and "V" is the voltage and "R" is the resistance

Substituting the given values we get,

$1700 = \frac{120^2}{R}\\\\1700 = \frac{14400}{R}\\\\R = \frac{14400}{1700}\\\\R = \frac{144}{17}\\\\R = 8.47 \approx 8.5$

Thus resistance in machine is 8.5 ohms
