5. Construct the circuit above on the breadboard. Have the professor verify the circuit. Using the handheld DMM and ELVIS DMM (if you are using ELVIS), measure each resistor value and the total resistance. Record the values in the table below. Compare the measurements and verify that they are within acceptable range.

Explanation / Answer

R1= 1000 ohm power = 1 KW = i2 * R1, i=1 A

R2= 3300 ohm power = 3.3 KW = i2 * R2 i = 1 A

R3= 2200 ohm power = 2.2 KW = i2 * R2 i = 1 A

it is clearly shown that all the resistance are connected in series hav same current of 1A

Hence measured resistnce by DMM is same as actual

ELVIS DMM shows measured resistance value = actual value
