A battery-operated DVD player uses 12 DC volts from AA batteries and draws a current of 3 A. Calculate the resistance.
4 ohms
the voltage is 12 DC and the current is 3 A, knowing that R=I divided by V, the resistance is would equal 4 ohms
To calculate the resistance of the DVD player, you can use Ohm's Law, which states that the resistance (R) is equal to the voltage (V) divided by the current (I): R = V / I.
In this case, the voltage is given as 12 volts (V) and the current is given as 3 amperes (A). Plugging these values into the formula, we have:
R = 12 V / 3 A
Simplifying the equation, we get:
R = 4 ohms
So, the resistance of the DVD player is 4 ohms.
