The Purpose of this report is to inform one about opens and shorts in a series-parallel circuit and their effects on individual voltages (E)and currents (I).
In this lab experiment, it was proven that in an open circuit, there is infinate resistance (ohms), which would limit practically all current from following the circuits path. It has also been shown that in the case of an shorted circuit, there is minimal resistance, therefore, maximun current is allowed to flow. Also, in combination curcuits, an open or a short in one branch can alter the current, resistance, and voltages throughout the remainder of he circuit. This experiment was designed to verify the following;.
1.) The charictaristics of series-parallel resistive circuits.
2.) The effects of an open scenario in a series-parallel resistive circuit.
3.) The effects of a short scenario in a series-parallel resistive circuit.
The procedure for this experiment is to start by measuring the individual values for each resistor used and to record them in table 18-1 (page 4). The next step was to connect the circuit shown in figur 18-3 (page 5).
1.) First, begin with calculating and the measuring the total resistance (RT or REQ) in the circuit and recordint the values in table 18-2 (page 4). Then, calculate the precentage of error and record it in table 18-2.
2.) Next, connect the circuit to your power supply and apply 15vdc. Then Calculate all voltage drops and individual component currents and record them in table 18-3 (page 4). .
3.) Then, use a voltmeter (BK Precision DMM .
2831-A) to take voltage drop measurements at each component in the circuit. Record the data in table 18-3.
4.) While keeping an applied voltage of 15vdc, remove R1 and replace with a short jumper wire. Take voltage drop measurements at all points in the circuit and record your data in table 18-3.
5.) Replae R1 and remove R2, repeat step 4 with respect to the shorted resistor.
