THE TRANSISTOR
The transistor has two main functions: A fast, electronic switch; A current amplifier. Transistors are process components. They are semiconductor devices and have a threshold voltage of 0.7 V. Below 0.7 V the transistor acts as an insulator (open switch). Above 0.7 V it acts as a conductor (closed switch). COMBINATION REACTIONS Turn on the Bunsen by sliding the control to the right of the Bunsen upwards. Click on the test tube and note the equation for the reactions taking place in its reaction details. One of these should involve the combination of iron with sulfur to give iron sulfide. Reload the simulation using the F5 key. Repeat the experiment usingzinc instead
INSTALLATION FAQS
A. Our CC3 installer has been designed to un-package a standard MSI bundle into an RM CC3 friendly folder structure, complete with placeholder program shortcuts. To install on a CC3 network server, simply run the CC3 installer and set the installation location to your Applications folder. Q. COMBINING LOGIC GATES Model 2. Open Yenka file Model 2. The circuit shows an electronic dice with the combination of LEDs representing the numbers. Press the push switch and describe what happens. Answer. The LEDs light up in the sequence of 1 to 6. Look carefully at the logic levels CAPACITORS - ACTIVITY Capacitors store electric charge. Think of a capacitor as a 'bucket' that can be filled up with charge. The charge stored depends on the size of the capacitor and the voltage applied across it. The capacitance of a capacitor is measured in farads, F. Real capacitors;the inside of
THE OP-AMP AS A COMPARATOR Introduction. The operational amplifier is an integrated circuit (IC). It is very useful in many projects because of its capabilities. In this lesson we shall investigate the use of the op-amp as a comparator and its use in sensing circuits. UNDERSTANDING NEUTRALISATION Answer. NaOH + HCl → H 2 O + NaCl. 2NaOH + H 2 SO 4 → 2H 2 O + Na 2 SO 4. One way of using these results to work out the concentration of the acid is to use the equation: PaVaCa = PbVbCb. 'a' refers to the acid, 'b' refers to the alkali. Pa is the number of H + ions available from the acid. For HCl, it is 1. TRANSISTOR AMPLIFIER In this model the red trace on the graph represents the voltage of the signal generator (the input to the amplifier) and the blue trace represents the output from the amplifier. It can be clearly seen that the output signal is amplified and inverted. To reload the model to its starting point, simply press F5 or select 'Reload' from the 'File'menu.

SOLUBILITY CURVES
Introduction. A solid (known as the solute) can dissolve in a liquid (known as the solvent) to produce a solution.There is a limit to how much solute can dissolve in a given amount of solvent at a particular temperature. A solution that contains as much dissolved solute as possible is said to be saturated.You are to investigate the maximum mass of potassium nitrate that will dissolve in 50 cm REACTIVITY SERIES AND ELECTRICITY Model 1. Open Yenka file Model 1. You will see that the screen shows a couple of beakers. They contain a salt solution. The salt solution also fills the salt bridge. This is a way of completing the circuit without wires. All salts when dissolved in water will conduct electricity. In the right hand beaker there is a rod made fromplatinum.

The charge stored depends on the size of the capacitor and the voltage applied across it. The capacitance of a capacitor is measured in farads, F. Real capacitors;the inside of
COMBUSTION - ACTIVITY Combustion involves the reaction of a substance - the fuel - with oxygen in such a way that heat and light are produced. We can think of a fuel as a substance that can be safely burned to produce heat and light. For combustion to take place, there must be a fuel, a supply of oxygen (usually air) and a source of heat to start and to maintain the IDENTIFYING UNKNOWN COMPOUNDS Task 1: Identifying the positive ions. The unknown samples and the apparatus provided. Open Yenka file Model 1. The easiest test to perform is the flame test. Describe the test below. Answer. Dip the metal rod into the substance, and then place it in the Bunsen flame. Watch the colour of the flame. Fill in the table with the correctcolours
NON-INVERTING AMPLIFIER The voltage gain for a non-inverting amplifier is: V out = V in (1 + R f /R in ) so for our circuit. V out = 1 × (1 + 50/10) = 1 × 6 = 6 V. Increasing the input voltage increases the output voltage, until a maximum is reached. In this circuit, with a 12 V supply to the op-amp, the maximum output is 9.99 V. The circuit as configured above will TRANSISTOR AMPLIFIER In this model the red trace on the graph represents the voltage of the signal generator (the input to the amplifier) and the blue trace represents the output from the amplifier.
