Explanation:

The circuit shown in the image is a parallel circuit which mean that the voltage of the source is equal across each resistance in the circuit because they are directly connected to the terminals of the voltage source.

The voltage across the 10 Ohms resistor is 120V

So, let's proceed to calculate the current

By using Ohm's Law

12A is the amount of current flowing through the 10 ohms resistor.

Current = (voltage) / (resistance)

The ends of the 10-ohm resistor are connected directly to both terminals of the battery.  

So the voltage across the resistor is the voltage of the battery ... 120 V.  None of that other stuff in the circuit has any effect on it.

Current = (120 V) / (10 ohms)

Current = 12 A .  (B)

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
