The current in an electrical conductor varies inversely as the resistance of the conductor. if the current is 30 ampere when the resistance is 600 ohms, what is the current when the resistance is 320 ohms? round to 1 decimal place.

Answer

56.25 ampere

Explanation

Current ⇒I

Resistance ⇒ R

I ∝ 1/R

I = k/R

k = IR

k = 30 × 600

   = 18,000

I = 18,000/R

 = 18,000/320

 = 56.25 ampere

the answer is 14ft

step-by-step explanation:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
