which is used to measure tiny currents‚ usually 1mA or less. Ammeter An ammeter is used to measure current. Voltmeter A voltmeter is used to measure voltage. Resistor (Fixed and Variable) Fixed Variable A resistor restricts the flow of current‚ for example to limit the current passing through an LED. A resistor is used with a capacitor in a timing circuit. This type of variable resistor with 2 contacts (a rheostat) is usually used to control current.. Capacitor: (fixed & variable)

to analyze the input and output signals produced by the amplifier. Because of the resulting output signals‚ which will be discussed further in other sections‚ this amplifier is essential to AC appliances requiring a certain amount of voltage and current gains. II. METHODOLOGY A. Materials and Equipment To construct the circuit‚ the electronic devices needed are as follows: capacitors of values 0.33 uF and 0.47uF‚ resistors of values 56k‚ 5.6k‚ 680 and 6.8k‚ a 2N3904 NPN transistor.

soft iron core. It can decrease the voltage (called a step down transformer). or increase the voltage (called a step up transformer‚ shown below). Alternating current is passed through the primary coil (the input) which creates a changing magnetic field in the iron core. The changing magnetic field then induces alternating current of the same frequency in the secondary coil (the output). A step up transformer has more turns of wire on the secondary coil‚ which makes a larger induced voltage

things such as cold air‚wood and plastic. Then there are things that conduct electricity and current flows through them‚ they are called conductors. examples of conductors are most metals like copper and steel. Other materials that are sometimes used as conductors are silver‚ gold‚ and aluminum. Copper is still the most popular material used for wires because it is a very good conductor of electrical current and it is fairly inexpensive when compared to gold and silver. Aluminum and most other metals
