Parts and their functions

• Battery (cells in series) (बैटरी (श्रेणीक्रम में सेल)) — Maintains the potential difference. Use 1, 2, 3, 4 cells to change V.
• Plug key K (प्लग कुंजी K) — Closed (plug inserted): current flows.
• Ammeter (in series) (ऐमीटर (श्रेणीक्रम में)) — Reads the current I through the wire XY.
• Nichrome wire XY (resistor) (नाइक्रोम तार XY (प्रतिरोधक)) — The conductor under test. V/I comes out constant = its resistance R.
• Voltmeter (in parallel across XY) (वोल्टमीटर (XY के पार्श्व में)) — Reads the potential difference V across XY.
