NOTE : You need to take a critical voltage reading, but you do not have a high impedance meter available.
Instead, you connect two lower impedance meters in series and place them across the component in question.
You add the readings shown on the two meters to get your measurement.
A piece of test equipment with a low input impedance can cause readings taken to be inaccurate.
To eliminate this problem, the input impedance of your test equipment should exceed the impedance of the circuit under test by what minimum ratio?
A. 1 to 1
B. 2 to 1
C. 10 to 1
D. 100 to 1
