Question 5

Consider a parallel combination of 3 resistors $R_1$, $R_2$ and $R_3$ with currents $I_1$, $I_1$ and $I_3$, respectively. Which of the following is true? (I = total current, Req = equivalent resistance of the circuit)

Accepted Answer

$I = I_1 + I_2 + I_3$

Answer

$R_{	ext{eq}} = R_1 + \frac{R_2 R_3}{R_2 + R_3}$
