Electronic – Calculating current through resistor

current-sourceresistors

What I know is with a current source, the current through the resistor should be the same as the source. But here I have two current sources so would this affect the value? I need to work out current through each of the resistors.

Best Answer

Since someone else has provided an answer, I shall provide a more intuitive approach.

Since the two current sources are in parallel, combine the 2A and 1A sources into one 3A source and then you have the canonical current divider circuit.

$$I_{R1} = 3A \dfrac{R_2}{R_1 + R_2} = 3A \dfrac{6}{3 + 6} = 2A $$

etc.
