R = 12+15+22 = 49kohm.
R = 10/2 = 5kohm.

TR = 49+5 = 54kohm = 54000 ohm.
V = 75V.

I = V/R.
I = 75/54000 = 1.38mA.

RT = 12+15+22 = 49.
RT of parallel = (10x10) /10+10) = 5
So, 49+5 =5 4
I = V/R. = 75/54 = 1.388888889 round off so the total current is 1.4 mA.

The source voltage 75v in the circuit.
VT = 75v
15krI = ?
IT = ?
The circuit is both series and parallel but total voltage is given.
R15kI = VT/R15k.
R15kI = 75/15000,
= 5mA.
