Question

1. which quantity can an oscilloscope measure? a resistance b current c voltage d power

Explanation:

An oscilloscope is a device used to observe and measure the waveform of electrical signals. It can directly measure voltage by displaying the voltage - time graph of an electrical signal. Resistance is measured by an ohmmeter, current can be measured with an ammeter, and power is calculated from voltage and current measurements.

Answer:

C. Voltage
