Week 10: Output Devices¶
Group Assignment¶
For this group assignment we had taken a power supply device, and a multimeter. The power supply we have is called , and its accuracy is to the … Whereas the multimeter, name of the device, had accurate to the …
Wiring these two together helped us understand the difference and the accurance between these two measuring devices.
On the multimeter there are 4 ports, for a pair of an anode and a cathode. Depending an the need we take out the cathode [the red one] and plug it into other ports. The anode [the black one] remains unchanged, and is not plugged out.
The Ground [Black Probe]:
COM: The "Common" port. The black lead always goes here
The Multi-Tool [Red Probe]:
V Ω Hz Temp Diode: this is your "everything else" port – use this for measuring voltage, resistance, frequency, temperature, and testing diodes
The Current Measures [Red Probe]:
10A: Only for measuring high current [up to 10 Amps]
mA: Only for measuring low current [milliamps]

Motor¶
We took a simple DC motor, and connected its two pins to…
As this is a direct current [DC] motor, it does not have designated anode or cathode, meaning it will work no matter the connection type to the pins.
Fan¶
We had done the same experiment with a simple blower fan.

Conclusion¶
It’s always interesting to discover something new. From a first glance it seems that these measuring devices are all the same, almost look the same, but just are different models. Changing these paradigms are always evoking that you cannot possibly know everything, even if you are a polymath.
Just about two weeks ago I had a brief though cross my mind about how does one measure the power consumption and estimate requirements for their device. While I did not give much though to it, and did not even search online, yet here I was, doing week 10.
