What is the first step in solving the problem of finding the equivalent resistance ($R_T$) of the entire circuit?
- Calculate the voltage drop across $R_1$.
- Find the current flowing through $R_2$.
- Combine $R_3$ and $R_4$ since they are in series. (correct)
- Assume a value for the total current.
If the current $I_1$ flows through $R_1$ and the total current entering the parallel branch of $R_2$, $R_3$, and $R_4$ is $I_T$, which equation correctly relates these currents?
If the current $I_1$ flows through $R_1$ and the total current entering the parallel branch of $R_2$, $R_3$, and $R_4$ is $I_T$, which equation correctly relates these currents?
- $I_1 = 2I_T$
- $I_1 = I_T$ (correct)
- $I_1 > I_T$
- $I_T > I_1$
