Final answer:
To solve for the current flowing through the 20 ohms resistor, we need to know the voltage across it. However, the given information does not provide the voltage, therefore we cannot calculate the current.
Step-by-step explanation:
To solve for the current flowing through the 20 ohms resistor, we can use Ohm's Law which states that current (I) is equal to voltage (V) divided by resistance (R). In this case, we need to know the voltage across the 20 ohms resistor. However, the given information does not provide the voltage. Without the voltage, we cannot calculate the current flowing through the 20 ohms resistor.
