Do we have to take into our consideration the resistance value factor only for a Resistor while designing our electrical circuits? Can Rated Power factor for our Resistor be a crucial factor? In this video […]
Working with LEDs is both fundamental and intriguing. However, the key to using LEDs effectively lies in understanding how to select the right resistor. This not only ensures you don’t murder your LEDs but also […]

This is the video I’ve been looking for!
one thing i get confused about is i thought current is DRAWN by whatever load is in the circuit. like how come when i charge my laptop (AC> using a 30W power brick, or a 90W power brick, it doesnt matter because its only drawing whatever current it needs to charge my laptop, how come the 90W power brick isnt burning up my computer battery by “pushing” too much amperage?
Why don’t we just talk volts, watts amps and ohms. What’s the p over I =v . Never understand it
(P)Power = (I)Current x (V)Voltage
Ty, i am new and learning the equations, knowing that “I” actually means current ahead of time will definitely save me a headache later
DID NOT help me figure out what size resistor I need
