Current through clamp on ammeter is measured in a non contact way.
To measure the current through 120 V supply, first we need to connect the load so that a current should flow in the circuit. Adjust your meter knob to AC current and Clamp the meter on a wire coming from 120V supply, and it will show you the total current drawn from the supply.
The way mentioned in question is a way to measure voltage not current.
If you try to measure current by that way, it will damage your meter.
Please thumbs up

In the circuit shown in the diagram below, two thick wires connect a 1.4 volt battery to a Nichrome (NIC) wire. Each thick connecting wire is 14 cm long, and has a radius of 9 mm. The thick wires are made of copper, which has 8.35+28 mobile electrons per cubic meter, and an electron mobility of 0.00434 (m (V/m). The Nichrome wire is 8 cm long, and has a radius of 4 mm. Nichrome has 9e+28 mobile electrons per cubic...

3. Explain the pros and cons of using aluminum wires instead of copper (4 points) 4. Compare the EMT and RMC raceways. When is RMC required? (3 points) 5. Calculate the voltage drop between a distribution panel supplying 120 V to an electrical device that is 200 ft. away from the panel (one circuit - one phase) if the amperage is current = 15 A and copper wires of AWG 14 are used. What is the Voltage available at this...
dwelling un 4. Type NM-B Cable enters a metal device box and is secured by a cable clamp at the bottom of the box. The cable is installed so the cable jacket extends "1/4 in. (6 mm beyond the cable clamp and free conductors begin at the end of the cable jacket a shown in Figure 1.39. If the device box has a depth of 3.5 in. (90 mm), the minimum permitted length of free conductor in this box is...

P48 In the circuit shown in Figure 18.110, the two thick wires and the thin wire are made of Nichrome. Figure 18.110 (a) Show the steady-state electric field at the locations indicated, including in the thin wire. (b) Carefully draw pluses and minuses on your own diagram to show the approximate surface-charge distribution in the steady state. Make your drawing show clearly the differences between regions of high surface-charge density and regions of low surface-charge density. (c)...
