Question

A car radio is rated at 35 watts when it is connected to a 14 v circuit. a) what is the resistance of the radio? b) what is the current the radio will draw?​

Answer 1

Answer:

current is I=2.5 amperes and resistance= 5.6 ohms

Explanation:

because we know that the one of the formula of power is p= VI

here,

35=14.I or I=35/14   = 2.5 amperes

then,

V=IR  or R=V/I    =14/2.5  = 5.6 ohms
