Calculate the total resistance of each circuit, the voltage across each resistor and the current going through each resistor for the circuits drawn below.
Calculate the total resistance of each circuit, the voltage across each resistor and the current going through each resistor for the circuits drawn below. After you have theoretically determined the resistances, voltages and currents, assemble each circuit using the two 100Ω resistors and the 200Ω resistor your group has been provided, and verify the voltages and currents using a multimeter.
You have only been provided one multimeter, so you will need to convert back and forth from a voltmeter to an ammeter. The currents flowing through the resistors will be in the milliamp range (10-3 Ampere). Therefore, you will need to use the (mA) and (COM) ports of the multimeter and the 200mA setting on the multimeter dial when you are using the multimeter as an ammeter.
Make sure each member of the group understands how to use a multimeter to measure voltage and current. A group member will be chosen at random to take measurements in Part II, and the group’s score will depend on the ability of the group member to measure the voltage and/or the current using a multimeter. Also be aware that your group will be allowed to blow one fuse in the multimeter. After you have blown your first fuse, each additional fuse will result in a grade deduction. Specifically if an ammeter is connected in parallel with a resistor, the current reading will be ambiguous, and the multimeter fuse may be blown.
Note the tolerance of each resistor is 1% so your measurements may not match your calculated values exactly, but they should be very close.
