CEN201: Lab Experiment 1 Ohm’s Law - Voltage and Current Dividers Kareem Abd Al Ghani 1065761 Mahmoud Hassan 1059613 Amer Alghazali 1062630 Mohammed Alloush 1065433 Amer Barhoush 1064958 Supervised By: Eng. Tasnim 1 Objectives Verify Ohms Law by showing the relationship between current and resistance and keeping voltage constant. Verify KVL (Kirchhoff’s Voltage Law). Verify KCL (Kirchhoff’s Current Law). 2 Experimental Setup and Equipment Used 1) Advanced Electronics Experiment Platform: Allows the user to attach an Electrical Networks Board to it and provide it with power. 2) Electrical Networks Board: Allows the user to create electrical circuits using wires. 3) Multimeter: An instrument used to measure electric current, voltage, and resistance. 4) Wires: Electrical conducting material used to connect circuit components. 3 Procedure first we put the equipment in the workplace then we implement the circuits as shown in the lab manual. 3.1 First Exercise: (Ohm’s Law) In the first exercise, we prepared a simple circuit using a voltage source and a resistor . 1. make sure the module power supply is off, so we do not encounter a short circuit which will ruin the electrical board, and so we do not get an electrical shock by unintentionally touching it. 2. we set up the resistor that its value can be changed and we did that by plugging in the shorting link into the given sockets as shown in Fig 4. 3. connect the resistor to the voltage source and we did that by plugging in a lead in the given sockets. 4. break the circuit to measure the current, then connect a Multimeter on DC current range between the given sockets, and we did that by plugging in the black cable into the common socket to the negative voltage input on the Multimeter, and we plugged the red cable into the positive socket to the positive current input on the Multimeter for it to be connected in series with voltage source and resistor . 5. set the initial value of the resistor to 100 ohm, and we did that by adjusting the variable resistor to 100 ohm before turning on the power supply on. 1
6. turn on the module power supply and measure the current and record it which we did by reading the value that was displayed by the Multimeter. 7. repeat the two previous steps with different resistance values. We can do that by turning off the power supply then changing the value of the resistance based on the table given in the lab manual.
