The r1 is 100v the r2 is 40v the r3 is 100v, total current is ma the switch is 12v i think i am not sure how to calculate the total current flow. Can somebody help me out its a parallel circuit.

Question is far from clear.
I am going to take a guess that we have three resistors in parallel
and a 12v supply.
I total = 12/100 + 12/100 + 12/40 amps
I total = 24/200 + 24/200 + 60/200 amps
I total = 148/200 amps = 740 milli amps

Assuming that your r's refer to resistors, Calculate net resistance. for parallel circuit, Reciprocal of net Resistance is equal to the sum of reciprocals of the individual resistors. Then apply the formula V=IR. and by the way, your 12v is not your total current. Its your potential difference, i.e, V!
