Question

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

Answer 1

30.25 W.

Step-by-step explanation:

Power in electrical circuit = volt x current

= 110 x 275 x 10⁻³

=30.25 W.

Answer 2

The power drawn equals 30.25 Watts.

Step-by-step 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* V`

Applying the given values we obtain power as

`P=275* 10^(-3)* 110\\\\\therefore P=30.25Watts`
