Question

# In parallel combination of resistors, the amount of current in the circuit

- Increases
- Decreases
- Makes zero
- None of the above

Hint:

### In a parallel combination of resistors, the** current flow increases** as they bear** less resistance.**

## The correct answer is: Increases

### In a parallel combination of resistors, the current flow increases.

- Ohm's law states that the current flow increases when the resistance decreases.
- In a parallel combination of resistors, the resistors will be separated in branches.
- So the resistance will be less in the parallel combination.
- Since the resistance offered becomes less, the current increases.
