If you reverse the direction of the voltage across a resistor (i.e., if the left side was 5V higher than the right side, change it so that now the right side is 5V higher than the left side), what will happen to the current running through that resistor? Group of answer choices The current will go to zero. The current will double. The current will also reverse direction. How should you connect voltmeters or ammeters to a device you want to measure the voltage across or current running through (respectively)? Group of answer choices Both voltmeters and ammeters should be connected in series. Voltmeters should be connected in series, while ammeters should be connected in parallel. Voltmeters should be connected in parallel, while ammeters should be connected in series. Both voltmeters and ammeters should be connected in parallel. Electrical devices which do not follow Ohm's law: Group of answer choices are known as non-ohmic devices. do not exist.
