Depending on the capacitor we are using it will have a cathode.For example if we take a unicapacitor(it will allow current on both sides) it will have a negative and a bi capacitor it will not have negative

How can you identify a cathode nigative to an LED?

LED has two pins,one is anode(positive) and the other is cathode(negative).The smaller pin is cathode(negative) and the longer pin is anode(positive).


Why do cathode rays move from the negative end of the tube to the positive end?

Because an electron carries a negative charge and in electricity, opposites attract. Particles with a negative charge will be drawn to the positive charge in the cathode tube.


What is meant by anode and cathode?

Anode is positive electrode which attracts the negative anions while cathode is the negative electrode which attracts the positive cations during electrolysis.


What do you call a negative electrode?

Cathode- is the negative electrode.Anode- is the positive electrode.

Compare an anode and a cathode?

The Anode (+) is what you connect the positive voltage to The Cathode (-) is what you connect the negative voltage to.


What is the charge of the particle in cathode rays?

The charge of the particle in cathode rays is negative. This was determined by J.J. Thomson through his experiments with cathode ray tubes in the late 19th century, which led to the discovery of the electron.
