Things were rosier back circa 2015 when I had a multimeter. It's a device for measuring current, voltage, and impedance. V=IR, that old standby equation. Not many people get it right, the concepts of V, I, and R. R (or Z) changes over frequency, and then there is capacitance C = Q/V, where Q is trapped or static current, or I. Capacitance and Impedance rule the electronics world, both changing with frequency (sine wave).
Voltage and current are not like blood pumping thru a circuit. Think of voltage as the rider of current and current as the horse. When the horse is strong, it leaps over impedance easily, when the rider is strong, it smashes current against the impedance, creating waste energy. When both are strong, there is little effect how they may be impeded by a further circuit stage.
So we get to the point of magnetism. Frequency of current-voltage gives rise to a magnetic field. The acceleration of Frequency of current-voltage gives rise to kinetic motion within a magnetic field. Think of magnetism as the gravity of potential difference. Then you will understand much of circuits.
Electromagnetism is a sustaining resonance between electric fields and magnetic fields, causing a beam of energy to form. This energy, when observed, is a particle, when followed with an instrument, appears to be a pulse, or wave. What we observe when we see an EM particle, is the granularity of force. Thus some speculated space-time emitted 'gravitons' (not within the scope of an E.E).
But if you think of force as granular, you will then be taken back to V=IR. None of the variables are force, but when you look at a circuit in any one state, you need to check the granularity, the V, I, R. You also need to know the Frequency, Capacitance, Horse:Rider.
Maybe I'm rambling. But this is the gist of electricity. And I hope you can understand it. And later, the transistor, digital / power concepts that you may ace E.E.
And yea, I do like my new multimeter. Back to coding.
