 The RMS and DC Voltage board lets the user compare the brightness of a lamp when operating from AC & DC. The AC is adjusted until the brightness is the same for both supplies. At this point the energy being delivered to the lamp by both supplies is the same. A scope is then used to compare the peak AC and the DC voltages. |
