This report covers the analysis of a DC circuit in order to determine unknown values within a circuit and covers the design process of a DC circuit when specific voltages are required and current and resistors values are unknown. Introduction This laboratory focuses predominately on DC circuit analysis and design although‚ as a result of this‚ many fundamental aspects of electrical engineering and circuit theory are brought to light.

it her side. H pins are for the heater with no polarity. Input pins A or B and output pins A or B can be connected it her way round. The coil heater inside the sensor can be easily heated with 5V DC. If pin A is connected to 5V DC through variable resistor VR1‚ use pin B as the output or vice versa. Both A and B pins can be shorted. In short‚ H pins are connected to positive and negative rails‚ A or B pin to 5V DC‚ and B o r A for output. The resistance value of GSI is different for various

Batteries‚ Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The electrons move because of the battery voltage. The current flows in the opposing direction of the electrons and the electrons flow towards the positive

is attached to the aluminum block with breadboarding for connection to the circuits built in the lab. The embedded resistance heater is used to heat the aluminum block. The heater is essentially a resistor that generates heat by the principle of Joule’s Law in which a current running through a resistor converts electrical energy into heat energy. Joule heating can be expressed by the relationship Q = I2 * R * t where Q is the heat (J) generated by a constant current I (A) flowing through a conductor

Investigation Into Temperature Sensors Introduction In this project I will be investigating how it is possible to use a temperature sensor to keep a greenhouse from changing temperature too much. This is intended to help plants live and grow in their optimum temperature. This will create a perfect temperature for the enzymes in the plants to work in‚ and therefore resulting in a maximum growth/production rate. This could be useful for gardeners who wish to grow plants as quickly as possible

connection as shown in Figure 5.1 to determine the whether the divider rule is correct or not by using theorical method. We set the power of generator to 9V and put 3 resistors in the circuit and label it as R1‚ R2 and R3‚ each with the resistance of 1k‚ 3.3k and 4.7k. We also added a voltmeter reading between each of the part of resistor to take the voltage reading. After all components in the circuits are connected correctly we click the green run button to let the voltage generator to supply power
