With higher frequencies, the microwaves also have more energy.  Having read the above passage, choose the right answer to the following question (choices are less energy or more energy. ):   Tim adjusted his microwave so that it was at a higher frequency. This resulted in the waves inside the microwave to have less energy or more energy.?
more energy.

When we add resistors in parallel to each other the total resistance decreases and the current increases.  Having read the above passage, choose the right answer to the following question (choices are increases or decreases ):   Eric adds resistors in parallel to a circuit. The total current increases or decreases?
increases
