As the multimeter to measure voltage, resistance and current in the electrical circuit
See how in practice multimeter measured the electrical voltage as measured by multimeter current, as measured by multimeter resistance.
Multimeter measures the electrical voltage
Measure multimeter electrical voltage, for example, the automotive battery. Car battery is a source of constant current and voltage at its terminals is approximately 12 V. Therefore DCV measurements use a multimeter sector.
Our actions when measuring the voltage will be such.
