Answer:
R = 40 ohms
Explanation:
Given that,
The voltage of outlet, V = 120 V
Current flowing through the device, I = 3 A
We need to find the Resistance rating of the power cord. Let the resistance is R. We know that,
Ohm's law, V = IR
Put all the values,
So, the resistance rating of the power cord is equal to 40 ohms.
Answer: 17 (a) 360,000 ms 18 (a) 0.245 s
(b) 4.800 kg (b) 500 cm
(c) 560.0 dm (c) 68.00 m
(d) 72,000 mg (d) 0.025 Mg
<u>Explanation:</u>
Use the following table. Note the direction you are going to:
Right means move decimal to the right. Left means move decimal to the left.
