1. install the device at a height of 5 cm in the container.2. Lux meter to measure the intensity of light. Save the results of screening device3. repeat the experiments repeated trial 3 like the quantity of water, but to be no. 2 and 10 15 20 25 30 Lux, respectively.Step 2-study the work of cutting equipment to cut the electricity the electricity in your home.1. study on parallel circuits to be used in the design of the device.2. connect a parallel device to the3. cut the power to the device try it with bulbs 5 volts.How to perform the experiment.1. per cycle to perform the experiment. By a 5-volt lamps brings the number of connected in parallel with the switch 1, with electricity as a power cord.2. assemble the power and breaker keys cut RI tech, all must be wired in parallel to each other.3. all devices are connected together. Cut the power equipment when come flooding in to the power cut. 4. make a 220 volt electrical supply into the circuit.5. to install equipment at 5 cm height from floor level. 6. when pouring water up to high levels, defined. It appears that the result "devices cut the power when the flood occurred," work and cut electricity in the home and comprehensive.
