17. Which of the following is the correct formula for finding power in a DC circuit? A. P = I2R B. P = VR C. P = IR D. P = V2I
netineya [11]

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 W that the electrical force do when it moves charges Q across a potential difference V:

W = V\cdot Q.

The power is the rate at which the electrical force do the work:

\displaystyle P = \frac{W}{t} = V \cdot \frac{Q}{t}.

On the other hand, current I is the charge through a cross-section of the circuit in unit time. By the definition of current:

\displaystyle\frac{Q}{t} = I.

\displaystyle P =V \cdot \frac{Q}{t} = V\cdot I.

Consider Ohm's Law:

V = I \cdot R.

Therefore

\displaystyle P = V\cdot I = (I \cdot R) \cdot I = I^{2}\cdot R.

Solve the inequality and write the solution in set-builder notation.<br> t-3&gt;-8
dedylja [7]

I have no idea what set builder is, so I'll just solve it if that's okay.

t-3>-8

First, to cancel out -3, you need to add it to both sides.

t-3>-8

+3  +3

t>-5

Find the missing term.
Oksi-84 [34.3K]

Answer:

-2 - 24i

Step-by-step explanation:

a + bi + (7 - 3i) + (5 + 9i) + 13i = 10 - 5i

a + bi + <u>7 + 5</u>  - 3i + 9i + 13i = 10 - 5i

                a + bi  + 12  + 19i = 10 - 5i

                         a + bi          = 10 - 5i - 12 - 9i

                                 a + bi = 10 - 12 - 5i - 9i

                                 a + bi = -2 - 24i
