Hi,
I am starting learning about the MOSFET. I am using dual Mosfet to control solenoids. I connected pump's positive terminal to 24V power supply, and the negative side connects to Mosfet's Drain terminal, and a diode to prevent back EMF. I have a 10K pull down resistor between gate and source, and able to turn on and off the solenoid by applying 5V to the gate.
The problem i have is, without applying 5V to the gate, i measure the voltage between the solenoid's positive and negative terminal i receive 4.5V, and it is suppose to be 0V. How can i remove this 4.5V?
Thank you much for your explanation.
