Experimental Verification Of Ohm's Law
A conductor of resistance R ohms is connected in series with an ammeter A, rheostat (variable resistance) and a battery B through key K. Voltmeter V is connected across the ends of the resistance to measure the potential difference across it.
Answer:
Ohm's law states that potential difference across a conductor is proportional to the current passing through it. The relation is given as V = i R , where is the resistance of the conductor.
electrical circuit, the current passing through most materials is directly proportional to the potential difference applied across them. Fig. 3-4: A circle diagram to help in memorizing the Ohm's Law formulas V = IR, I = V/R, and R= V/I. The V is always at the top.
Ohm's law formula
The resistor's current I in amps (A) is equal to the resistor's voltage V in volts (V) divided by the resistance R in ohms (Ω): V is the voltage drop of the resistor, measured in Volts (V). In some cases Ohm's law uses the letter E to represent voltage.
