Answer:
Choice A. P = I² · R where
- P is the power in the DC circuit,
- I is the current through the circuit, and
- R is the total resistance of the circuit.
Step-by-step explanation:
Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work
that the electrical force do when it moves charges
across a potential difference
:
W =
.
The power is the rate at which the electrical force do the work:
.
On the other hand, current
is the charge through a cross-section of the circuit in unit time. By the definition of current:
.
.
Consider Ohm's Law:
.
Therefore
.
Answer:
the answer is 9 11/15 or 26/15 in improper fraction form.
Answer:
37.5
Step-by-step explanation:
split in the middle, 5×5=25/2=12.5
12.5= triangle
5×5=25
25=square
12.5+25=37.5

Answer:

Step-by-step explanation:
Brain correctly use a method of completing the square to solve the equation:

His First Step is to: Take the Constant Term to the Right Hand Side

The Next Step Would be to:
- Divide the Coefficient of x by 2
- Square It
- Add it to both Sides
In this case, the Coefficient of x = 7
- Divided by 2 =

- Squaring It, we have:

It is this number
that is added to both sides in the manner below:
