Question

If a CD player uses a 12-V battery and draws 2.0 amps of current, how much power does it use?

Answer 1

Answer:

The power is 24 watt .

Explanation:

Given that,

Voltage V= 12-V

Current I = 2.0 A

Using ohm's law

The current is directly proportional to the voltage.

In form of power,

The power is the product of the Current and voltage.

Formula of the power is defined as,

$P = I\times V$

$P = 2.0\times12$

$P = 24\ watt$

Hence, The power is 24 watt .
