The two resistors are connected in parallel. The resistance of the first resistor is 2 ohms, the resistance of the second

The two resistors are connected in parallel. The resistance of the first resistor is 2 ohms, the resistance of the second is 6 ohms. The current in the first resistor is I1 = 3 A. (I is the current). What is the current in the second resistor?

Condition:
R1 = 3 Ohm
2 = 6 ohm
I1 = 3 A
To find :
I2-? AND
Decision :
since the connection is parallel, it follows that:
U-constant (U = const) – constant voltage.
U = I * R – Ohm’s law.
U1 = I1 * R1
U1 = 3 * 2 = 6 (V)
U1 = U2 = 6 V – because the voltage is constant in parallel.
I = U / R – Ohm’s law.
I2 = U2 / R2
I2 = 6/6 = 1 (A)
Answer: 1 A. 3) I2 = 1 A.
