Question

6. A conduction tester is made by a bulb. But it does not detect weak currents
How can we make another tester which can detect weak current?
​

Answer 1

Answer:

hope it will help you .

Explanation:

If weak current flows through the circuit then bulb in it will not glow. In order to detect weak current we use LED or may use another effect of electric current that is it produces magnetic effect also so we can use this property of electric current to detect weak current.                                                                                                     please mark me brainlist.

Answer 2

Using galvanometer we can make a tester that can detect weak currents.
