*Figure 1.0 Diagram of Experiment*
**Explanation of Diagram:**
The diagram shows a combination of series and parallel resistor circuits with a voltage source \( \varepsilon \) of 9.0V. The resistors \( R_1 \), \( R_2 \), \( R_3 \), and \( R_4 \) are connected as follows:
- \( R_1 \) (5Ω) is in series with the combination of \( R_2 \) (3Ω) and \( R_3 \) (7Ω) in parallel.
- \( R_4 \) (15Ω) is in series with the aforementioned combination.
- The circuit has three currents: \( I_1 \) flowing through \( R_1 \), \( I_2 \) flowing through \( R_2 \), and \( I_3 \) flowing through \( R_3 \).
**Procedure**
**Part 1: For the circuit shown in Figure 1.0 above,**
*Given Values:*
- \( E = 9.0V \)
- \( R_1 = 5\Omega \)
- \( R_2 = 3\Omega \)
- \( R_3 = 7\Omega \)
- \( R_4 = 15\Omega \)
Using the method of finding the equivalent resistance for a series-parallel circuit:
a. Determine the magnitude of currents \( I_1 \), \( I_2 \), and \( I_3 \) respectively.
b. Find the potential drop across each resistor.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff5306076-2d35-4889-8514-a0af824cbe60%2F1b3f3bd0-2e65-4a34-8647-7b7a7c8cc9d3%2Fhjotipj_processed.png&w=3840&q=75)
