Physics
A person connects his household appliances in series. Which of the following is true ?
- Each appliance operates independently
- The current in the circuit is reduced as resistance increases
- Each appliance does not operate at its rated voltage
- Both (2) and (3)
Answer
Both (2) and (3)
Reason — When a person connects his household appliances in series:
- the total resistance increases as more appliances are added, which would lead to a decrease in current according to Ohm's Law (V = IR).
- the voltage across each appliance will vary depending on its individual resistance and the total voltage supplied by the source. Each appliance may not receive its rated voltage due to voltage division across the appliances.
