Answer:
300 w
Explanation:
swim this question we have an equation w = 21 25 - 2012 I square which represents the power w where w is the power in watts and 120 volt circuit is there which has a resistance of 12 ohm when current I is flowing through the circuit the voltage resistance and current is what is the maximum power in war that can be delivered in this circuit so we have to find out the maximum value of power that can exist in the circuit with 120 volts AC circuit and 12 homes of resistance ok so to find the maximum value of this in an equation we need to find vi we can the best way is we can find out the Maxima Abhishek creation and how do you
find the maximum to find the maximum we can differentiate this equation with respect to I and when the equator when we will equip the differentiation of this equation 20 the value of I that will obtain that will be obtained after doing this will be the maximum for this equation let me show you how that is differentiate DW by D I can we differentiate this this equation with respect to I we get 120 - 24 I know what we have to do this week with this 20 now 120 - 24 I = 20 with this I = 25 we get the value of equal to 55 is the maximum for this equation which means that if we put the value of I
45 we replace if the Avengers equation replace iPhone 5 will get the maximum value of w which is what you wanted right we wanted the maximum power in watts letters replace I buy 5 this equation the equation is 120 I -12 I square be replaced by 5 we get the answer as 300 w this is our answer
