In a series circuit, there are two resistors R1, R2, where R1 = 4 ohm In a series circuit, there are two resistors R1 and R2, in which R1 = 4 Ω. When the resistor is installed in the circuit with voltage of 6V after series connection, the actual power consumed by R2 is 2W. Calculate the resistance value of R2! Clear thinking, the right person is much better than the right person within 1 hour

Let R2 resistance be r with formula P = I ^ 2 * r
Total current I = 6 / (4 + R)
2={6/(4+R)}^2*R
The solution is r = 2 or r = 8
Remember to add a lot of points
