Activity-Phet_Ohm's Law
Now, change the values of voltage of source, resistance of resistor & note the value of current. Check with the theory (Ohm’s law).

Now, change the values of voltage of source, resistance of resistor & note the value of current. Check with the theory (Ohm’s law).
The above observations can also be verified through Ohm’s law.
For example, for the first case,
Voltage = 12 V ; Current = ____A ; Resistance = 4 Ω ;
By Ohm’s law, V = I R
ie, I = V / R = (12 V) / (4 Ω) = 3 A
ie, 3 Ampere current flows through the circuit when we apply a potential difference of 12 Volts across a resistor of resistance 4 Ω.
