Why does zinc and copper create a higher voltage than copper and copper in a circuit?

It is very weird and I am gonna help. Zinc and copper create a higher voltage than copper and copper because zinc has a higher voltage than copper so copper plus zinc equals more than copper plus copper.

Are tantalum capacitors polarized?
Yes, tantalum capacitors are polarized capacitors.This means that when connecting them in a circuit, you must connect the anode to the higher positive voltage than the cathode.
Which has a higher heat capacity copper or styrofoam?
Copper
What happens when zinc is dipped in a copper sulfate solution Zinc is higher on the activity series than copper.?
Zinc becomes plated with copper.
Copper sulfate plus iron equals?
The iron is higher in they reactivity scale than copper , Therefore the copper will be replaced by iron to make iron sulfate and copper by itself.
Which weighs more copper or silver?
Copper has a higher density then silver. So a cubic inch of copper weighs more then a cubic inch of silver.
Is gold used in circuit breakers?
Certainly not in the case of high-voltage circuit breakers. Probably not in low-voltage circuit breakers, as copper is a better conductor and has a higher melting point.
What benefit is there for getting higher open circuit voltage?
There is no particular benefit for having a higher open-circuit (or 'no-load') voltage. In fact, an ideal voltage source would have no internal resistance and, therefore, its open-circuit voltage would be identical to its closed-circuit voltage.
What is open circuit voltage in a Fuel Cell?
A: All batteries will eventually fail when that occurs the voltage out of then can be zero or higher voltage when new, In that case the battery has failed but if you measure the output it will have a higher voltage because there is no load or open circuit as soon as the load is applied the voltage just disappear this condition is called open circuit voltage
What is the higher voltage at the electrode before the arc is struck called what is it's advantages to welding?
Open circuit voltage is the voltage at the electrode before striking an arc (with no current being drawn). The higher the open circuit voltage, the easier it is to strike an arc because of the initial higher voltage pressure.
When a circuit is inductive the current has what voltage?
This doesn't make sense, "current" is "amperage" so the higher the voltage the lower the amperage, and the lower the voltage the higher the amperage.
High voltage will trip a circuit breaker?
A higher voltage means that a higher current will flow in the same load. It is the current that causes the breaker to trip.
In the electrical circuit the higher the voltage the lower the?
Amps Ohm's law states the current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
What is the purpose of capacitor in power supply higher than rated voltage?
The voltage marked on a capacitor is its MAXIMUM SAFE WORKING VOLTAGE. The capacitor will work in a circuit at any voltage lower than that, but it may fail at any higher voltage.
Why does higher resistance have a larger voltage drop across it?
In a d.c. circuit, voltage drop is the product of resistance and current through that resistance.
What happens to amps when you increase the resistance of a circuit?
If you don't change the voltage between the ends of the circuit,then higher resistance in the circuit means lower current (amps).
What will increase the voltage in a circuit?
There is a way to use capacitors to increase the voltage in an ac circuit. It increases it by about 50 %. It was used to increase the voltage going to motors. It is seldom used now that it is much easier to run a higher voltage line into a place of business. It does not work for Direct Current.
Will voltage or current be higher in a circuit during short circuit?
Since a short circuit is, essentially, a zero impedance connection between nodes, the current in a short circuit is limited only by the ability of the source. In the case of an ideal voltage source connected to an ideal short circuit, you would have infinite amperes.
