Characteristics 1. Observe the lights. (number lit and brightness)
2. Describe the effect of moving bulb unit 1 just enough to break
the circuit of the rest of the bulbs. 3. Describe the effect of
moving bulb unit 2 just enough to break the circuit of the rest of
the bulbs. 1 Slide 12 Slide 13 Looking at Electricity - Quantative
Characteristics 1. Volts - Pressure that cause the current to flow.
The potential difference across a conductor in an electric field 2.
Amperes - Rate of the current flow. One ampere is approximately
equivalent to 6.2415094810 18 electrons moving past a boundary in
one second. 3.Ohms - Resistance of the conductor (wire or hose) to
the flow. A device has a resistance of one ohm if one volt causes a
current of one ampere to flow. 4. Watts - Power produced due to the
pressure and the flow of the electrons. 4 0 Slide 14 Parallel

Combined Parallel Series Circuit Remember in series circuits
amperage is constant and in parallel circuits it is additive.
Therefore if we add the amperage for the series circuit to the
amperage for the parallel circuit we should get the amperage for
the entire circuit. (0.16 + 0.27 = 0.43) 0.16 1b 3a 2(2+3) Series
