A stereo speaker has a resistance of 8I© and has a power draw of 32W. How much current is going through the speaker?

Answer 1

Current = 2 Amperes

Step-by-step explanation:

Given the following data;

Resistance = 8 Ohms

Power = 32 W

To find the amount of current going through the speaker;

Mathematically, power can be calculated using the formula;

Power = current² * resistance

Substituting into the formula, we have;

32 = current² * 8

Current² = 32/8

Current² = 4

Taking the square root of both sides, we have;

Current = √4

Current = 2 Amperes
