This is my calculation.I made this in wordpad,so it will be easy to posthi,
That looks like a clip from a electronics text book, why have you posted that and not your actual calculations.?

It looks like your answer is 2.3 amps but there is another character between the '3' and the 'A' for amps that i cant quite make out. But 2.3 amps is correct rounded to two significant figures, although we usually strive for a few more digits or at least one more. The more exact result is slightly less than 2.3 amps.View attachment 237112is this right???
