A battery is connected to three resistors of resistances 12Ω, 6Ω and 2Ω, as shown. [Figure showing a circuit diagram with a 3 A battery connected to a parallel combination of 6Ω and 2Ω resistors, which is in series with a 12Ω resistor] The current from the battery is 3 A. What is the value of the ratio power dissipated in the resistor of resistance 6Ω / power dissipated in the resistor of resistance 2Ω?
