Question
State two characteristics of resistances in the series circuit.
Advertisements
Solution
Characteristics of resistance in series:
- The sum total of resistances in series increases with an increase in the number of resistors.
- The potential difference remaining constant, the current in series circuit decreases with the increase in the number of resistors in series.
- All the elements in series circuit work simultaneously. If the circuit is broken anywhere between the elements, none of the elements work.
