I am supposed to find a way to charge a metal plate with a defined charge ( in nanocoulomb) and it must have a + charge so basically i want to know if this way is correct and applicable, and if there is any limitations.
- Get 2 metal plates and a dielectric ( the dimensions of the plates and thickness of dielectric will determine the capacitance of this parallel plates capacitor)
- connect to electrodes to the two plates.
- connect the electrodes to a voltage source. Determine voltage according to desired charge (C=Q/V)
- connect a voltmeter to the circuit.
- after the voltage on both plates is equal ( capacitor is charged ) , disconnect the capacitor from the source of voltage.
- Using an isolator, separate the plates from the dielectric.
- As the charge will be in nanocoulomb it wouldn't be so hard to overcome the attraction between the 2 plates.
- The desired plate is the one connected to the positive pole.
