Calculating the AC voltage and current across resistor and fuse
Not without knowing more about L2. But from the values I calculate it to be about 26 Ohm. Then the I and V make sense as V R7 = 550/(550+26)*220 = ~210V. And I is 220/(550+26)= 0.38A. The resistance of the rest of the circuit (D4,D5 etc) is high compared to the resistance of the bulb and disappears in the accuracy of the measured current value.
