Concept explainers
Use the UT33B multimeter and check the voltage of the batteries and the resistance of, light bulb and resistors supplied.
- Voltage of the battery is measured to be 1608 mV, The scale used to measure voltage is 2000mV on the UT33B multimeter
- Resistance of the bulb is measured to be 0.24 ohm, The scale used to measure resistance is 200 ohm on the UT33B multimeter
- Resistance of the resistor1 (R1) is measured to be 15.2 ohm, The scale used to measure resistance is 200 ohm on the UT33B multimeter
- Resistance of the resistor2 (R2) is measured to be 27.2 ohm, The scale used to measure resistance is 200 ohm on the UT33B multimeter
i) Justify your selection of the scale used.
ii) Quote all results in the standard form i.e. must include uncertainty.
iii) For the resistors how does your measurement compare to the nominal value. Clearly explain how you established if there was an agreement or not.
