Question

A subwoofer needs a household voltage of 115 V to push a current of 6 amps through its coil

(circuit). What is the resistance of the subwoofer?

Answer 1

R = 19.17 ohms

Explanation:

Given that,

The voltage of a subwoofer, V = 115 V

The current through its coil, I = 6 A

We need to find the resistance of the subwoofer. Let it s R. Using Ohm's law to find it such that,

V = IR

So,

`R=(V)/(I)\\\\R=(115)/(6)\\\\R=19.17\ \Omega`

So, the resistance of the subwoofer is 19.17 ohms.
