Alternatively, you can use a shunt resistor in series and measure the voltage drop to calculate current (I=V/R).

One method involves employing a shunt resistor, a low-resistance component placed in series with the circuit.

By measuring the voltage drop across this resistor, which is directly proportional to the current flowing through it according to Ohm's Law (V = IR), the current value can be determined.

Alternatively, a current probe can be utilized. This specialized tool directly senses the magnetic field generated by the current flow and converts it into a proportional voltage, which is then displayed by the oscilloscope.

Is it possible to use an oscilloscope for this?
