A) 1.0A
B) 5.0 A
C) is about 1.3 A
D)4.0 A
E) cannot be calculated

wouldn't the current in each be the same (in series)?

what u mean it wil be the same as wat ?

I=U1/R1 =U2/R2 =80/20=4 A
D)4.0 A

As it's a series combination therefore the current remains same throughout. We are given R1=20ohm and V1= 80v so according to formula I=v/R answer is 4A.

In a series circuit, the amperage at any point in the circuit is the same. This will help in calculating circuit values using Ohm's Law.
Therefore, the current of the 20 resistor is same in the 60 resistor.
I= 80/20= 4a
60 resistor= 4a
