If the current throught a 6 Ω resistor is 7 A, what is the power absorbed by the resistor? Answer to the nearest 1 W.

290W

Explanation:

The relationship between power (P) absorbed by a resistor, the current (I) flowing through the resistor and the value of resistance is given by;

P = x R

This means that the power absorbed by a resistor is the product of the current flowing through it and the value of its resistance.

Given;

I = current flowing = 7A

R = resistance =  6 Ω

Substituting the values of I and R into the equation above gives;

=> P = x 6

=> P = 49 x 6

=> P = 294W

Converting this to the nearest 1W gives 290W.

Therefore, the power absorbed by the resistor is 290W

answer: the correct answer id option(d).
