Question

A battery-operated DVD player uses 12 DC volts from AA batteries and draws a current of 3 A. Calculate the resistance.

A) 4 ohms
B) 9 ohms
C) 15 ohms
D) 36 ohms

Answer 1

R=V/I
so R=12/3

The answer is A) 4 ohms
Hope this helps!

Answer 2

Option (A) is correct.

Step-by-step explanation:

We use ohm's law

`V= i R`

V= voltage=12 volts

i= current=3 A

R= resistance

so i= V/R

i=12/3

i=4 ohms

Thus the resistance resistance of the DVD player = 4 ohm
