Question

Draw neat circuit diagram for below mentioned requirements in electrical circuit: (i) One lamp controlled by one switch. (ii) One lamp, one fan, one two pin socket controlled by separate switches.

Answer 1

Sure! I'll describe the circuit diagrams for the requirements you've mentioned.

### (i) One Lamp Controlled by One Switch

**Components Needed:**
1. Lamp
2. Switch
3. Power source (AC supply)

**Circuit Diagram Description:**

1. **Power Source:** Represented as a pair of AC supply lines, typically labeled as L (Live) and N (Neutral).
2. **Switch:** Connected in series with the lamp. This means that when the switch is open (off), the circuit is broken, and the lamp will not light up. When the switch is closed (on), the circuit is complete, allowing current to flow to the lamp.
3. **Lamp:** Connected to the switch and neutral line. When the switch is on, the current flows from the live line, through the switch, through the lamp, and back to the neutral line, illuminating the lamp.

**Circuit Diagram:**

```
  AC Supply
    L  ----o------ Switch ---- Lamp ----- N
```

### (ii) One Lamp, One Fan, One Two-Pin Socket Controlled by Separate Switches

**Components Needed:**
1. Lamp
2. Fan
3. Two-pin socket
4. Three separate switches
5. Power source (AC supply)

**Circuit Diagram Description:**

1. **Power Source:** Represented as AC supply lines, labeled L (Live) and N (Neutral).
2. **Switches:** Three switches, each controlling one of the following:
   - Switch 1 controls the lamp.
   - Switch 2 controls the fan.
   - Switch 3 controls the two-pin socket.
3. **Lamp:** Connected in parallel to the power source through Switch 1.
4. **Fan:** Connected in parallel to the power source through Switch 2.
5. **Two-Pin Socket:** Connected in parallel to the power source through Switch 3.

Each device (lamp, fan, and socket) is connected in parallel, allowing independent control by its respective switch.

**Circuit Diagram:**

```
  AC Supply
    L  ----o--- Switch 1 ---- Lamp -----
    L  ----o--- Switch 2 ---- Fan -----
    L  ----o--- Switch 3 ---- Socket ----
    
    N  ---------------------------------
```

### Notes:
- In a practical application, ensure that all connections are properly insulated and that the circuit adheres to local electrical codes and standards.
- For the two-pin socket, ensure that the load requirements (e.g., appliances) are compatible with the socket's rating and that proper grounding is considered if needed.

Answer 2

Here’s how the circuit diagrams would look for the two scenarios you described:

### 1. **One Lamp Controlled by One Switch**
- **Components:**
  - **Lamp**
  - **Switch**
  - **Power Source (AC Supply)**

- **Circuit Diagram:**
  - The **live (L)** wire from the power source connects to one terminal of the switch.
  - The other terminal of the switch connects to one terminal of the lamp.
  - The **neutral (N)** wire from the power source connects directly to the other terminal of the lamp.
  - **Operation:** The lamp will turn on or off when the switch is toggled.

### 2. **One Lamp, One Fan, One Two-Pin Socket Controlled by Separate Switches**
- **Components:**
  - **Lamp**
  - **Fan**
  - **Two-Pin Socket**
  - **Three Switches** (one for each device)
  - **Power Source (AC Supply)**

- **Circuit Diagram:**
  - The **live (L)** wire from the power source connects to one terminal of each switch.
  - The other terminal of each switch connects to the respective device (lamp, fan, and socket).
  - The **neutral (N)** wire from the power source is connected directly to the neutral terminal of the lamp, fan, and two-pin socket.
  - **Operation:** Each device can be controlled independently by its respective switch.
