Wire Intersections Two connected wires Two wires not connected
Parallel Connection Disconnect one bulb. What happens to the other bulb?
Series Connection Disconnect one bulb. What happens to the other bulb? What are differences between series and parallel connections?
Capacitors Electrolytic capacitors (polarized) Ceramic capacitors (non-polarized)
The Symbols for Capacitors Polarized Non-polarized
Capacitance – Measuring the Capability of a Capacitor “Farad” is the unit for measuring capacitance. The symbol for Farad is “F.” 1 μF = 0.000 001 F = 1 x 10-6 F 1 nF = 0.000 000 001 F = 1 x 10-9 F 1 pF = 0.000 000 000 001 F = 1 x 10-12 F
