OBJECTIVE The objectives of this experiment are to investigate and verify the Thevenin’s theorem and to investigate and verify the Norton’s theorem. EQUIPMENT Resistor 100Ω‚ 1kΩ and 4.7kΩ‚ digital multimeter(DVM)‚ bread board. INTRODUCTION Some circuits require more than one voltage source. Superposition theorem is a way to determine currents and voltages in a linear circuit that has multiple sources by taking one source at a time. the current in any given branch of a multiple-source linear

Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is

1 Ohm’s Law For a resistor R‚ as in the Fig. 1 below‚ the voltage drop from point a to b‚ V = Vab = Va − Vb is given by V = IR. I a b R Figure 1: Voltage drop across a resistor. A device (e.g. a resistor) which obeys Ohm’s Law is said to be ohmic. The power dissipated by the resistor is P = V I = I 2 R = V 2 /R. 1.2 Kirchoff’s Laws Consider an electrical circuit‚ that is a closed conductive path (for example a battery connected to a resistor via conductive wire)‚ or

Current‚ Voltage and Power * Electricity is the flow of electric charge. We can describe the flow of electric charge in several ways. These include the quantities Current‚ Voltage and Power. Current * Current (I) is the rate of flow of Charge Carriers‚ such as electrons. Current is usually thought of as moving in the direction of positive charge‚ so from the positive power supply to the negative. However‚ since in metals it is electrons that carry electric charge‚ the actually flow is opposite

this circuit‚ transistor T1 and associated components form the audio signal preamplifier for the acoustic signals picked up by the condenser microphone and converted into corresponding electrical signals. Resistor R5 and capacitor C3 decouple the power supply of the preamplifier stage. Resistor R1 biases the internal circuit of the low-voltage condenser microphone for proper working. The audio output from the preamplifier stage is fed to the input of the medium-power amplifier circuit via capacitor
