Is iron a anode or cathode?
it is an anode
What kind of sign does anode has?
An anode is positive, Cathode is negative. As such, an anode would usually be denoted as + If that is what you meant.
Which electrode in the anode is galvanic cell?
Zinc is the anode.
The anode in an electrochemical cell has this charge?
The Anode in electrochemical cell has negative charge (-ve).
How does sacrificial anode protect a submerged pipeline?
Just have a crack at Sacrificial anode in wikipedia.org.
A diode does what?
A diode is a semiconductor meaning it will conduct from anode to cathode if the anode is held positive. Reversing the polarity Will in effect block current flow.
What does diode do?
A diode is a semiconductor meaning it will conduct from anode to cathode if the anode is held positive. Reversing the polarity Will in effect block current flow.

In a potato battery is the zinc negative or positive?
Its confusing because its assumed the Anode positive which isn't always the case in electrochemical devices. In the potato battery. Zinc Side Negative. [-] Anode Copper Side Positive [+] Cathode Further reference: WikiPedia: http:/enzperiodzwikipediazperiodzorg/wiki/Anode '...A widespread misconception is that anode polarity is always positive (+). This is often incorrectly inferred from the correct fact that in all electrochemical devices negatively charged anions move towards the anode (hence their name) and/or positively charged cations move away from it. In fact anode polarity depends on the device type, and sometimes even in which mode it operates, as per the above electric current direction-based universal definition. Consequently, as can be seen from the following examples, in a device which consumes power the anode is positive, and in a device which provides power the anode is negative.'
When diode is connected to ohmmeter What happens?
A: Depends on meter leads voltage polarity and the diode itself orientation to these polarity. One way is should show a low impedance + to anode Reverse the diode it should be hi impedance
How do you wire Bi-color LEDs?
Treat each color as a separate LED and wire accordingly. Be sure to observe the polarity of the component (anode and cathode +/-)
How do you wire Bi color LEDs?
Treat each color as a separate LED and wire accordingly. Be sure to observe the polarity of the component (anode and cathode +/-)
How do you test polarity with a multimeter?
A: To begin with the leads polarity of the meter must be ascertain. Assuming the red is positive voltage then that lead will have a positive potential to check a diode connect the red lead to the anode and the black to the cathode and it should read some Resistance
Polarity of cathode and gate terminalscr when switch on?
The SCR switches on when the gate is more positive than the cathode at the same time the anode is more positive than the cathode.
What types of anode?
the two types of anode is stationary anode and rotating anode
How LEDS are connected in seven segments display?
A: the LED can have all cathode tied together or all anode tied together. To alight them up all you need is the proper polarity input for each.
In a simple cell the cathode or the anode is more reactive?
Anode(:
