its a circuit i've made, i need to calculate the current in it but i think im doin it wrong...

my lecturer said if i find out the current pulled by the 4026IC then i can use that to calculate the entire current pulled but i'm not to sure as the LED would be excluded...

anyway here it is:





4026 IC spec:

http://eu.st.com/stonline/books/pdf/docs/2038.pdf

Can you figure out the Current?

I dont have the circuit anymore either i'm afraid as it was handed in last week could've just used a multimeter otherwise
