The current through the bulb will be 0.5 A. The principle of ohm's law is used in the given problem.
Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
This current-voltage connection may be expressed mathematically as,
The Equation of Ohm's Law is found as;
V=IR
[tex]\rm I = \frac{V}{R} \\\\ \rm I = \frac{120}{240} \\\\ I= 0.5 \ A[/tex]
Hence the current through the bulb will be 0.5 A.
