10. Looking at Electricity - Qualitative 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

12. 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 6.24150948×1018 electrons moving past a boundary in one second. • 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
