For emample, if you are dealing with Copper and Zinc, you first take the half equations Cu2+ + 2e- --> Cu +0.34 Zn2+ + 2e- ---> Zn -0.76 then, you decide which one is reduced and which one is oxidized, the one with the more positive voltage is reduced, so in this case the copper is reduced. the overall reaction changes to Zn- ---> Zn2+ + 2e +0.76 Cu2+ + 2e- --> Cu +0.34 ---- Zn + Ni2+ ---> Ni + Zn2+ + 0.5 you add the voltages and get 0.5 as an experimental voltage

How do you calculate income yield?
You must first calculate the theoretical yield of your product using the balanced equation. The crude yield is divided by the theoretical yield and multiplied by 100.
How do you calculate current and voltage passing through light globes?
You can't "calculate" both. If you know the wattage & the line voltage then I = P / E and vice-versa.
How many amps is equal to 270 cca?
If you know the voltage you can calculate the amps. . Ampere I = power P / voltage V .
How do you calculate 3 phase motor kWH where voltage are 440 and amps are 11?
To calculate kWh a time component is needed for the hours.
Low voltage lights equivalent to 110 volt lights in watts?
Watts are calculated by multiplying the voltage by the amperage. To calculate the wattage you need both these numbers
Is there a theoretical limit to high voltage?
Theoretically there is no limit to the voltage of an electrical current.
What is needed to calculate the voltage across a device?
you calculate a voltage circuit by taking it apart and findng the circuit and calculate the voltage and then resible it.
How do you calculate the excitation voltage and current of an alternator?
formals to calculate exciation voltage of alternator
How do you calculate transformer voltage ratio test?
Secondary voltage / primary voltage
What size breaker do you need for 3kva?
To calculate an answer a voltage must be stated.
How do you calculate income yield?

How do you calculate voltage drop for starting motor current and how to get the starting pf?
How do you calculate voltage drop for starting motor current
Why is it impossible to calculate an exact theoretical yield of soap?
measurement inaccuracy
How do you calculate line regulations?
no load voltage - full load voltage by full load voltage
How do we calculate voltage?
V = I x R V = voltage, I = Current, R = Resistance or it can be calculate like this V = P / I V = Voltage, P = Electric Power, I = Current
Can you calculate power by multiplying voltage and current?
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
How do you calculate predictions?
The theoretical yield is determinef by the study of the chemical reaction involved.
