Why does an oscilloscope reveal faults that a multimeter cannot?

Select one answer.

• Because a multimeter is always broken and can never give a correct reading of any kind, so any measurement it produces on any circuit must be discarded and only a scope can ever be trusted for a plain steady voltage.
• Because it draws a signal's voltage against time, so its shape — level, timing, edges, and noise — is visible, where a meter reports only a single averaged number that flattens ripple, glitches, and edge detail away.
• Because a scope measures current directly while a meter can only ever measure voltage, so the scope alone can show how much current each part of the circuit draws at every instant in time.
• Because a scope needs no probe connection to the circuit at all and reads every signal wirelessly from across the bench, so it can see nodes a meter's leads could never physically reach on the board.
