How Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of

eventually level off as well before reaching zero. Apparatus & Procedure: This experiment required the use of a 1.5 V D-size battery‚ a battery holder‚ a digital multimeter‚ a 220μF capacitor‚ a 100 KΩ resistor‚ a DPDT switch‚ connecting wires‚ alligator clips‚ and a stopwatch. After the apparatus was set up and the multimeter was connected to the capacitor‚ the first procedure required the capacitor to be charged via throwing the switch towards the battery and simultaneously starting the timer

produce a flow of electrons‚ which is what an electrical current really is. A battery has two terminals‚ one positive and one negative. They are usually marked by plus and minus signs‚ so you can tell which is which. After the battery is assembled‚ a multimeter / voltmeter can be used to check the generated voltage. In order for a more visible effect to be produced‚ a few orange cells connected in series can be used to power a standard LED (Light Emitting Diode). Flashlight bulbs are generally not used

cell. I will be using a 1.5V battery in the experiment. I will measure the voltage and current using multimeters. Calculation method I intend to rearrange the equation ‘ε=Ir+IR’ to form ‘V= -Ir +ε’ and then draw the y=mx+c graph equation to find EMF and internal resistanc`e. The y axis intercept measures EMF and the gradient gives you internal resistance. Projected main sources of error The multimeter has some inaccuracies: Resistance is accurate to 0.1 ohms (+/-0.8%)‚ Current is accurate to 0.03 A

Introduction I have chosen to investigate a factor that affects the output of a potential divider circuit. A potential divider is resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage. A resistor is a device having resistance to the passage of an electric current which affects the output voltage (Vout). The factors that I could investigate are changing the resistance of r2 and record the output (Vout)‚ or use a light-dependent resistor (LDR) and change

As soon as the DC level goes out of the predefined voltage range‚ your system should change the gear accordingly and engine rpm should be demonstrated by making use of the analog multimeters in the laboratory.
