SOLUTION :
I varies directly as E and inversely as R, write as:
If E = 100, I = 20, R = 20, Solve for k,
- 20 = k(100)/20
- 20 = 5k
- k = 20/5
- k = 4
So, If k = 4, E = 220, R = 20, Solve for I,
- I = (4)(220)/20
- I = [tex]{\boxed{\green{\sf{44 }}}}[/tex]
ANSWER :
- Therefore, the current that will flow through the machine if 220 volts will be used and the resistance will not be changed i.e. 20 ohms is 44 amperes.
hope this helps
