Ohm’s Law states: The potential drop across a resistor is proportional to the current passing through the resistor: V ∝ I. Ohm’s Law applies only to resistors with constant resistance; that is, to resistors whose resistance is the same no matter what current is passing through them.For such resistors: V/I =R (where R is constant). Ohm’s Law can be written: V = IR (where R is constant).

While doing Ohm’s law experiment, a student observed that the pointer of the voltmeter coincides with 15th division, the observed reading is (a) 0.75 V (6) 0.075 V
The SI unit of r esistivity is ohm meter ( Ω m). In this experiment, we study these factors in an electric circuit by employing dif fer ent r esistors (wir es) of dif fer ent lengths and ar eas of cr oss-section. Using Ohm’s law, the r esistance of a conductor in an electric cir cuit can be determined by measuring the current through it and ...

Ohm’s Law states that “If the physical conditions such as temperature, pressure, etc., remain the same during the experiment, then the current (I) flowing is directly proportional to the potential difference (V) across the ends of the circuit.” Mathematically, V= IR or . Where, 1.
To verify Ohm's Law, we can conduct an experiment using a simple circuit with a resistor, a power supply, and an ammeter and voltmeter to measure current and voltage respectively. Step by Step Solution: Step 1. Set up a circuit with a power supply, a resistor, an ammeter in series, and a voltmeter in parallel with the resistor. Step 2
