The little speaker in a portable radio is labeled 16 Ohm's , 0.1 W. To what current does that correspond?(adsbygoogle = window.adsbygoogle || []).push({});

I'm kind of confused where to go with this one. what i know is this, 1 watt=1volt*1amp, but where do i go from there?

Do I have to use Ohm's law somehow? V=IR.

So does VI=.1 and R=16 ohms? am i supposed to be able to solve for I from that or something?

im just confused as to where to go next with this problem. This is the first problem i've had with Watts.

Thanks for any tips.
