The voltage in the circuit decreases if: a) the current increases b) the current decreases

The voltage in the circuit decreases if: a) the current increases b) the current decreases C) the resistance decreases d) the voltage cannot be changed

In order to answer this question, you need to refer to one of the common formulations of Ohm’s law regarding voltage in a circuit, which says:

U = I × R

It follows from this that it is possible to change the voltage in the circuit, which means that the answer option D is not correct.

Let’s consider other options. We know that you can reduce the product by decreasing the values of one or several factors that form it – in this case, the current strength and resistance This is stated in answers B and C, therefore, they are both correct.
