According to Ohm's Law:
V = IR
=> R = V/I 
Where, V = potential difference, I = Current and R = Resistance
=> R = 4.6/0.25 = 18.4

The resistance of the bulb can be found using Ohm's Law, which states that the resistance (R) is equal to the potential difference (V) divided by the current (I):

R = V / I

Plugging in the given values:

R = 4.6 V / 0.25 A

R ≈ 18.4 Ω

Therefore, the resistance of the bulb is approximately 18.4 Ω.
