Leviton’s industry leading locking devices, such as our Black & White line of industrial grade plugs and connectors and receptacles, offer superior performance, long lasting reliability and other features that are backed by a lifetime warranty. 20 Amp, 125/250 Volt, NEMA L14-20P, 3P, 4W, Locking Plug, These industrial grade, grounding devices have a super tough nylon body that resists damage from severe Impact, abrasion and chemicals. Solid brass blades and contacts feature improved conductivity, low resistance, low heat, and long life. Internal wiring chambers isolate individual conductors to prevent flashover, arcing, and stray strands of wire.

Ohm’s Law

You will learn about “Ohm’s Law” in this video. German physicist Georg Simon Ohm stated that the electric current flowing through a metallic wire is directly proportional to the potential difference across its ends, provided its temperature remains the same. This law is called Ohm’s law. Let us verify Ohm’s law with the help of an activity. Take a nichrome wire of about 0.5 m, a milli-ammeter, a voltmeter, a switch and 3 cells of 1.5 volts each. First, let us connect 1 cell with the wire, voltmeter and milli-ammeter. When we pass current through the circuit, we can see that the current is 120 mA (0.12 A) and the potential difference is 0.3 V. Now, connect 2 cells instead of 1 cell. The current through the wire is 200 mA (0.2 A) and the potential difference is 0.5 V. When we connect 3 cells in this circuit, the current is 300 mA (0.3 A) and the potential difference is 0.75 V. Observe all the values together. With increase in number of cells, the values of V and I also increase. However, the ratio of voltage to current is constant in all the readings, i.e. 2.5 V per ampere. Hence, we understand that voltage is directly proportional to current. This verifies the Ohm’s law. The V I graph is a straight line passing through the origin. V is proportional to I or V/I = Constant. This constant is R where R is the resistance of the metallic wire at its given temperature. Hence V/I = R or V = IR.
