what is the total resistance of this circuit?
and what is the total current thru the v battery?
First, solve the resistance of the parallel resistors and then add that to the series resistor to get total resistance:
/R(p) = /R + /R = / + / = / + / = /
Thus R(p) = / = . ohms
Thus R(t) = R(s) + R(p) = + . = . ohms
Since V=iR we know V and R so:
i = V/R = /. = . amps (to places)
