नीचे दर्शाए गए परिपथों में, वोल्टमीटरों तथा अमीटरों के पाठ्यांक होंगे:

Ideal voltmeter has infinite resistance and ideal ammeter has zero resistance. Both circuits measure the same terminal voltage \( 10\text{ V} \) across the \( 10\,\Omega \) resistor, so \( V_1 = V_2 \) and current \( i_1 = i_2 \).
