When magma reaches the surface of the Earth, it is called lava. Most volcanoes occur along or near the margins of tectonic plates, where plates move away from each other or collide. We have a number of resources relating to volcanoes, available from … Webthe correct output of 120VAC. Figure 6c shows a measurement between neutral and ground while figure 6d indicates a measurement between line and ground. The voltage reading between neutral and ground is 57.6VAC while line to ground is 62.9VAC. This is because the neutral is not tied to the chassis ground in this case so it actual “floats” above dichroic extract powder
