Hi there, I have enjoyed your Basic Electronics series very much and even used it for teaching! So great work! 🙂👍Haven't you considered making some more videos with simple circuits, also created in Everycircuit! I could for example envision some with crystals, LF amplifiers, RF amplifiers, emitter followers, common base amplifiers, transformer circuits, mixer circuits, simple oscillators like Pierce and Collpits types, a Wien Bridge oscillator, a Wheatstone Bridge, a Maxwell Bridge and other DC or AC measurement bridges, Low pass, High pass and Bandpass filters, circuits with opamps and equivalent circuits illustrating how capacitors, inductors and resistors work at high frequencies. What do you think?

Regarding the geometric properties of the resist, is the external area of the resist (the brightness area) the only factor, or does its behavior differ with respect to thickness?

Hi, great videos. I'm teaching an extra-curricular club course in my school. I'm trying to create a dark-detector for my students to take home. I've seen many videos on youtube, but none of them explained how their LDR worked. It seems we have different LDR and ratings. Can you explain how to make a night light with an LDR? Please include the power ratings of the LDR and the resistors that are necessary, which no one else does. Thanx

Hi. I'm trying to find out about LDR's. Nobody ever seems to answer, maybe they just don't know the answer. If I introduced and LDR to the tamper circuit of an average alarm system, and with a laser pointer pointed at it, would the current flow freely enough to keep the alarm system running without a fault? And if I then turn off the laser, would the resistance be great enough to trigger the alarm?

Can Someone help me, I’m so confused because for example in street lights as it gets dark there is more resistance. How I would interpret that is if there is more resistance then less current can flow through the circuit meaning that there is less light. But this doesn’t seem to be the case?

@daruscole1586 Жыл бұрын
Are they used in digital cameras (still/video) to put the image into electrical signals (analog/digital)? I think I have read/heard that variable capacitors are used that vary capacitance with the amount of light in cameras so maybe this is a thing of the past.

アキ健太郎 the resistance & the voltage of the LDR increases when there is no light. That is because the semiconductor is not being excited by light.

@chrish758327 күн бұрын
I’m confused. If more light lowers the resistance, that would mean that there would be more current flowing through the circuit, powering the load (an LED for example). So, if there’s less light, there’s higher resistance, lowering the amount of current in the circuit. So the LED would turn off. At least, that’s how I’m understanding it. Is that right? Because that doesn’t make sense to me. I thought that you would want to power an LED or other kind of light source when it got dark?

@balajiganesan43996 жыл бұрын
bro if it is a bright morning, you will have more light, so its resistance is lower and the current can easily flow through the resistor and power the street light. And at night, there is darkness and you have higher resistance , the current cant flow through the resistor and doesnt power the street light.
