Liquid silver nitrate and liquid sodium chloride combined forms the substance silver chloride.
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.
What your going to do is take away the lowest number form the highest and subtract. Thats your answer...
