Explanation:

Step1: Identify resistors in series

From the circuit, we have $R_0 = 450\Omega$ and $R_{L1}=150\Omega$.

Step2: Calculate total equivalent resistance

For resistors in series, $R_T=R_0 + R_{L1}$. So $R_T=450 + 150=600\Omega$.

Step3: Calculate total circuit current using Ohm's Law

Ohm's Law is $I=\frac{V}{R_T}$, where $V = 120V$ and $R_T = 600\Omega$. So $I=\frac{120}{600}=0.2A$.

Step4: Calculate voltage across $R_0$ using voltage - divider rule

The voltage - divider rule for $R_0$ is $V_{R_0}=\frac{R_0}{R_T}\times V$. Substituting values, $V_{R_0}=\frac{450}{600}\times120 = 90V$.

Step5: Calculate voltage across $R_{L1}$ using voltage - divider rule

The voltage - divider rule for $R_{L1}$ is $V_{R_{L1}}=\frac{R_{L1}}{R_T}\times V$. Substituting values, $V_{R_{L1}}=\frac{150}{600}\times120 = 30V$.

Answer:

$R_T = 600\Omega$, $I = 0.2A$, $V_{R_0}=90V$, $V_{R_{L1}} = 30V$
