Question

Study the following statements:

1. A fuse in a circuit prevents damage to the circuit due to overloading.
2. Total resistance in a circuit increases due to overloading.
3. During short circuiting the current in the circuit abruptly increases.
4. In order that each appliance has same current, they are connected in parallel to each other.

The correct statements are:

Options

• a and b

• b and d

• a and c

• a, c and d

A short circuit occurs when a low-resistance path bypasses the normal circuit, causing an uncontrolled surge of current.
