You plug a microwave oven into a 20 amp electrical circuit. the microwave uses as much as 12.5 amps . How many amps are available on this circuit for other appliances?

Correct result:

I =  7.5 A

Solution:

$I=20-12.5={\displaystyle \frac{15}{2}}={\displaystyle \frac{15}{2}}\text{ A}=7.5\text{ A}$
