Question

Calculate the electrical power used by the radio (a resistor) that draws a 275 mA current from a 110 V outlet

Answer 1

Answer:

The power drawn equals 30.25 Watts.

Explanation:

The power across a resistor that draws a current 'I' amperes from the source and has a potential difference 'V' across it is given by

$P=I\times V$

Applying the given values we obtain power as

$P=275\times 10^{-3}\times 110\\\\\therefore P=30.25Watts$

Answer 2

Answer:

30.25 W.

Explanation:

Power in electrical circuit = volt x current

= 110 x 275 x 10⁻³

=30.25 W.
