Q5. How to check Continuety
Ans. 
Continuity can be checked by testing the flow of electrical current through a circuit.
• Use a multimeter to test for continuity by setting it to the continuity or resistance mode.

• Place the multimeter probes at each end of the circuit or component being tested.

• If the multimeter beeps or shows a low resistance reading, there is continuity.

• If there is no beep or a high resistance reading, there is no continuity.
