B6

An ideal ammeter should have

A) Zero resistanceB) Infinite resistance

B4

Is it possible to measure the current generated by the power supply using the scope?

A) No, it only measures voltage

B) Yes, just turn the knob on the scope from “V” to “I”

C) Yes, put a resistor in the circuit and measure the voltage across it.
