current

Hello, I am new to hardware design. I am designing measurement circuit for Impedance Spectroscopy of electrochemistry cell. I need to measure the current coming from electrodes which have range from few milliamperes to few nanoamperes. as literature suggested, the equivalent circuit for...

Hi! I have a very old Kavo Brand German made micro motor (probably made around 1970s-80s). It it a very well built tool but the power supply is suffering from some problem. When the brushed motor hand piece is connected and powered on, it will spin but in constant pulses (maybe 1 second on, 1...

Hi! I would need some clarification with a BLDC DC bus current.(Marked With IL on the picture) The motor is a BLDC with trapezoidal commutation and 20kHz PWM. I beleive that current is the 20 kHz PWM with an amplitude of the maximum current of the motor. Is it right or I misunderstood...
