1. an increase in voltage causes the flow of electric current to.
a. decrease
b. increase
c. remain unchanged

2. an increase in resistance causes the flow of electric current to
a. decrease
b. increase
c. remain unchanged

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.

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

c. magnitude and direction
