I've just started tinkering and I'm having trouble with a pretty basic concept: reading and selecting components.
I have some push buttons that say ACDC 24V — does this mean in need 24V of AC -> DC power for the component?
I have another push button that says: UI: 440V AC15 Ith: 10A DC13 —...
I've set up an arducam mini 2MP plus with a nrf52DK (similar to an arduino for this set up) to take pictures.
Ive got the board and camera working when the camera is wired with the VCC line and GND wired directly into the boards 3.3v line and ground pins. The arducam uses about 100 mAmps when...
Greetings. A vendor selling TP4056-based 5 V charging modules for Li-ion cells specified the following resistance values and resulting current for selecting the current-programming resistor:
R (kΩ)
I (mA)
30
50
20
70
10
130
5
250

To solve this question all I know is I had to change the delta source to star shape (wye), then to find the current is using ohm law's with the voltage divided by the impedance which in the same line
I'm confused with this question, does the position of the source in delta and impedance matter...
Quarantine project: Adapting a Sony BFV-20W viewfinder
Scroll down to skip the background info
As a cinematographer, I've always really felt most comfortable shooting with a viewfinder. However modern electronic viewfinders all exist in the "prohibitively expensive" class of filmmaking...
Okay so my question relates to biasing and threshold voltage in a MOSFET amplifier. So in an amplifier the clipping occurs when the signal hits the power rails according to all the reading I’ve done. That’s how much voltage swing you supposedly have before clipping. So if you have an 18 volt...
Say there are 3 buses of:
Bus 1: Slack bus with a voltage source of E=1.0 and phase of 0°
Bus 2: a generator and a load.
Bus 3: a load.
The line impedance are given below:
z12 = 0.05 + j0.1
z13 = 0.02 + j0.05
z23 = j0.05
z11 = -j100
z22 = infinity
z33 = -j40
The generators and loads are given...

Assume we provide a load with its rated voltage, suppose it should draw the current it need at such voltage level. However, what if we place an additional resistor in series with the load, can the load still draw the same current as it needed?
I am tasked with confirming a report that said we had a large voltage spike (~400v I believe) when turning some equipment on.
I went and put the oscilloscope on our main that is in the same box for the switch for the equipment.
I throw the switch and see my measurements react a little but I...
I am having this new Function generator - AFG3000C
I am having difficulty in understanding certain terms related to this FG.
I have tried online searches, but I couldn't get what I was looking for. Being a newbie, I request you all to help me understand my queries in simple terms.
Could you...
2 generators are connected to the bus below.
Given
V1 = 300V, 50Hz
V2 = 400V, 60Hz
When the switch is opened, calculate
i) the maximum and minimum voltage across both light 1 and 2.
ii) peak voltage across both lights
iii) maximum number of light pulsation
How do I solve the issue above? Any...
I have a servo and an actuator, both connected to a breadboard, needing 7v and 12v power respectively. I don't want to use batteries. How would I adjust the wall plug 120v to 7v and 12v respectively? There are technically adapters on amazon, but I am not sure how to connect them to my breadboard.
I am supposed to calculate the theoretical values for ”natural frequency”, currents and voltages at electrical resonance for this circuit.
I should use the measured values for the resistance and the inductance of the coil. Also the measured value of the capacitance to the capacitor. The...
Hello,
I would never thought I could not understand a circuit made out of diode but here I am.
1-the first circuit is two diode in series, when i measured the voltage between the them I found it half the voltage of the source which is not logic for me!!! as there is no current flowing through...
