An ultrasound machine uses 1.64 × 105 watts of power. If it draws 12.0 amps of current, what is the resistance?

Respuesta :

Answer:

Explanation:

Power of electrical circuit = I² R where I is current and R is resistance

Putting the given data

1.64 x 10⁵ = 12² x R

R = 1.139 x 10³ ohm

= 1139 ohm .

Answer:

r=1140ohms
