The resistance of the resistor is 24Ω and the current going through the resistor is 1,8 A. What is the power for the resistor?

Question

Question 5 Answer

A.
7,41 W

B.
77,76 W

C.
43,20 W

D.
0,14 W

Answer 1

To calculate the power \( P \) consumed by a resistor, you can use the formula:

\[ P = I^2 R \]

where:

• \( I \) is the current (in Amperes)
• \( R \) is the resistance (in Ohms)

Given:

• \( R = 24 , \Omega \)
• \( I = 1.8 , A \)

Now, substitute the values into the formula:

\[ P = (1.8 , A)^2 \times 24 , \Omega \] \[ P = 3.24 , A^2 \times 24 , \Omega \] \[ P = 77.76 , W \]

So, the power for the resistor is \( 77.76 , W \).

Therefore, the correct answer is: B. 77.76 W
