For 29, yet it’s asking for current, which is “I” in the Ohm’s Law equations. So you have to look at what information you are given, and then look at the Ohm’s Law pie chart to find the formula that will work, given what you know and what you’re trying to calculate.
Similarly for 28 – we are asking for the resistance you would expect to read on your meter. You’ll find that by using an Ohm’s law formula that finds “R”, and uses the information we give you in the problem statement.
