How to check for continuity
this is for when you are given multiple equationsPlug in the number in the inequalityIf the two equations give you the same thing, the function is continuous and the limit exists
To check for continuity, you will need a digital multimeter, which is a device commonly used for testing electrical circuits. Here’s how to check for continuity using a digital multimeter:
1. Turn off the circuit breaker or disconnect the power source to the circuit you are testing.
2. Set your digital multimeter to the continuity setting. This is usually indicated by a symbol that looks like a sound wave or an arrow pointing towards a vertical line.
3. Touch the black lead to one end of the circuit, and the red lead to the other end. If there is continuity, your multimeter will emit a beeping sound. If there is no continuity, it won’t beep.
4. If there is no beep, check your multimeter’s battery, as it may be dead or low. If the battery is not the issue, check your leads for any signs of damage or debris. Clean or replace the leads as necessary.
5. Test multiple points along the circuit to ensure that there is continuity throughout the whole circuit.
6. Once you have confirmed that there is continuity, turn the circuit breaker back on or reconnect the power source, and test the circuit to see if it is functioning properly.
By testing for continuity using a digital multimeter, you can quickly and easily identify any breaks in an electrical circuit, which can help you troubleshoot and fix any issues.
