You are decreasing the resistance of the two connections when you squeeze the probes. Also, it will vary depending on how salty and damp your fingers are from sweat.
i hope it will helpfull...☺️
A measurement device that can assess several electrical characteristics is a multimeter. The term "volt-ohm-milliammeter" (VOM) refers to a multimeter that has the ability to measure voltage, resistance, and current. This is because the device has voltmeter, ammeter, and ohmmeter functions.
- The user can adjust the multimeter to read different values, such as milliamps (mA) of current, voltage (V), and resistance (), using the selection knob.
- Two of the ports on the front of the device are connected with two probes each. Common, abbreviated as COM, is often linked to the circuit's ground or "-" terminal.
Your finger's surface area comes into more contact with the probe ends when you squeeze it. This is due to the fact that the tips of your fingers will extend further down the probe as they wrap around it. Additionally, you reduce the ridges in your finger print pattern, increasing the surface area in touch.
