WebFeb 24, 2024 · 3. Your first drawing shows the polarity of the voltage across the diode when the top terminal of the transformer is positive, and diodes D3 and D4 are reverse biased, and not conducting. D1 and D2 will have anode positive, and be conducting - they are apparently ideal diodes as they are shown with zero volts across them. WebInsert one of the leads into the longer vertical opening in the outlet. This is a 0-volt neutral contact. Insert the other lead into the shorter vertical opening. This is a 120-volt hot contact. If a reading appears on your multimeter, then the polarity is correct because voltage is being transferred from the hot contact to the neutral contact. the range kids table
