The current flowing in the 4 ohms resistor connected in series with 5-ohm resistor is determined as 1.0 A.

Equivalent resistance of the circuit

The equivalent resistance of the circuit is determine as follows;

Rt = R1 + R2

Rt = 4 ohms + 5 ohms = 9 ohms

Current flowing in the 4 ohms resistor

The current flowing in the 4 ohms resistor is determined from Ohms law as shown below;

V = IR

I = V/R

I = 9/9

I = 1.0 A

Since the circuit is in series arrangement, same current will flow in 5 ohm and 4 -ohm.
