### Electrical Circuits: Understanding Voltage Drops and Power Dissipation

#### Problem 6

The circuit contains two groups of resistors:
- **Group 1**: The group of 5 resistors on the left.
- **Group 2**: The group of 2 resistors on the right.

A constant voltage is applied across the entire circuit. Determine which group of resistors experiences a larger voltage drop.

#### Diagram Details:
- The diagram shows resistors marked as "R".
- The resistors in Group 1 (left side) form a complex network with both series and parallel connections.
- Group 2 (right side) consists of two resistors in series.

##### Options:
a) Both have the same voltage drop  
b) None of the above  
c) Group 1  
d) Group 2  

---

#### Problem 7

Two identical resistors are connected in parallel across a 100V battery. When only one of the resistors is connected, the energy dissipation rate is \( P_0 \).

Calculate the rate of energy dissipation when both resistors are connected to the battery.

##### Options:
a) \( \frac{1}{2} P_0 \)  
b) \( 2 P_0 \)  
c) \( \frac{1}{4} P_0 \)  
d) \( 4 P_0 \)  

This exercise aims to deepen understanding of voltage drops across complex circuits and the effect of parallel connections on power dissipation.
