The power generated by an electrical circuit (in watts) as a function of its current $c$ (in amperes) is modeled by:
$P(c)=-20(c-3)^2+180$
**Which currents will produce no power (i.e. $0$ watts)?**
*Enter the lower current first.*
Lower current: [[☃ numeric-input 1]] amperes
Higher current: [[☃ numeric-input 2]] amperes
