Experiment 1 — Verify Ohm’s Law

Try it in the interactive lab🔊 Audio

Topic: Physics · Class 10 · Electricity: Ohm’s law and resistance

Aim: Plot a straight-line V–I graph and obtain a resistance of 5 Ω .

Daily: Every appliance rating, every fuse and every wire thickness in your home is chosen using this one relationship between voltage, current and resistance.

Question: Where must an ammeter be connected, and why?

Exp: An ammeter has very low resistance and measures the current flowing through the circuit.

Question: The slope of a V–I graph gives…

Question: A voltmeter is connected…

Exp: It measures potential difference across a component.

Question: Resistance of a wire increases if you…

Question: A 12 V supply drives 0.4 A. The resistance is…
