Answer:

1.33A in each resistor.

Voltage across 3 ohms = 3.99v

Voltage across 3 ohms = 7.98v

Explanation:

Total resistors in series = 3 + 6 = 9 ohms.

From Ohm's law,

V = IR, where V is the voltage of the battery, I is the current from the battery and R is the total resistance.

12 = I × 9

I = 1.33A

Since the resistors are connected in series then same current 1.33A in each resistor.

Different voltage will be across each resistor since the connection is in series.

Using Ohm's law, V = IR

Voltage across 3 ohms = 1.33 × 3 = 3.99v

Voltage across 6 ohms = 1.33 × 6 = 7.98v
