To figure out capacitor polarity the stripe on an electrolytic capacitor tells you the negative end. For axial leaded capacitors (in which the leads come out of the opposite ends of the capacitor), there may be an arrow that points to the negative end, symbolizing the flow of charge.
Visual Examples Leaded radial capacitors: The negative terminal is marked with a stripe or band running along the length of the body. PCB-mounted radial capacitors: Often show clear markings with a longer lead for the positive terminal and a band for the negative terminal. Identifying Markings Longer lead: Indicates the positive terminal.
Electrolytic capacitors, a type of polarized capacitor, usually have clear markings indicating the positive (anode) and negative (cathode) terminals. The negative terminal is typically marked with a minus (-) sign, a series of minus signs, or a colored stripe. The positive terminal, on the other hand, is often longer than the negative one.
Check the voltage rating. If there is room on the body of the capacitor, the manufacturer usually lists voltage as a number followed by a V, VDC, VDCW, or WV (for "Working Voltage"). This is the maximum voltage the capacitor is designed to handle. 1 kV = 1,000 volts.
Since an electrolytic capacitor is polarised in nature, we can identify its polarity in the following ways: By checking the polarity signs (+ or -) next to any one of the terminals. Connect ‘+’ with the positive terminal and ‘-’ with the negative one of the circuit.
Observe the waveform on the oscilloscope display. Correct polarity: The waveform should show a characteristic charging curve, starting at zero voltage and exponentially increasing to the supply voltage. The positive terminal of the capacitor will be where the voltage increases.
