Using the Ohm's Law Concept Builder is quite simple. You will be presented with information regarding the current in a circuit. You will then be asked to determine the new current that would result if the voltage and/or resistance were changed by some factor. Answer the question by tapping on the new current field and using the pop-up Number Pad to enter your answer. Press on the Enter key on the Number Pad to enter your answer and activate the Check Answer button. If you need to change your answer, repeat the process. Once you are satisfied with your answer, tap on the Check Answer button. Your answer will be evaluated and your Progress Report will be updated.
