Answer:
1. B. Increase
2. A. Decrease
Explanation:
To understand this issue, we need to put some values and using the ohm's law we can corroborate the two situations.
Ohm's law:
Now for the voltage we will use V = 110 [V], for resistance R = 10 [ohms]
Replacing the values we have:
Now let's double the voltage 220 [V]:
Therefore the current will be increased.
Let's do the same for the resistance if originally we have R = 10 [ohms]
Now let's double the resistance 20 [ohms]:
Therefore the current will be decreased.
