Question

The current in a simple electrical circuit is inversely proportional to the resistance. If the current is 20 amperes ( an ampere is a unit for measuring current) when the resistance is 3 ohms, find the current when the resistance is 7.4 ohms.

Answer 1

8.1081 amperes

Answer 2

how do you write that as a proper fraction?

Answer 3

\[I _{1}R _{1}=I _{2}R _{2}\]\[20*3=I _{2}*7.4\]\[I _{2}=8.1081\]

Answer 4

It says to write is as proper fraction or mixed number?

Answer 5

you can write the answer \[I _{2}=8.1\]

Answer 6

I tried it said it was wrong and i have to type it in fraction form :/

Answer 7
