❥ANSWER
Electric power:-
The rate of doing work or rate of consumption of electrical energy is called Electric Power. If W is work done in time t, then P=W/t.
S.I unit is Watt(W). One watt of power is consumed when 1 A of current flows at a potential difference of 1 V.
The commercial unit of electrical energy is a kilowatt-hour (kWh).
1kWh=3,600,000J=3.6×106J
Represented as P=I2R and P=V2/R
One kilowatt-hour is defined as the amount of energy consumed when 1kW of power is used for 1 hour.

Answer:
-2
Step-by-step explanation:
here
a= 1, b = 0, c= -3, d = 2
in case of cubic polynomials
sum of roots = -b/a
= 0
product of roots = -d/a
= -2
sum of sum and product of roots = 0+(-2)
= -2
