Device requires a terminal voltage of 12 volts and a current of 2 Amps. Design a circuit using as many 3 ohm resistors as needed to properly power this device. The EMF is 24 Volts.
Ohm's law: V=IR
The Attempt at a Solution
I know how to find equivalent resistance, but I don't know how to dissipate some of the voltage, in this case, get the voltage from 24 down to 12.
