What if we let E = IR^2t? Since these cells are indentical, they have the same resistance, so, the current should be different. (And since voltage is the work required for an electron to go through a certain passage, if the two cells are identical, it should require the same amount of energy...

I see it like this: When photoelectric effect occurs, energy from light sources are used to: - Free electrons - Produce electricity Since the energy from the light sources here are equal, if the amount of energy used to free electrons of one photocell is higher than the other one, then the...

Wait a minute, isn't the electrical energy produced is the energy that photons that gave (E(e) = hf - W), so if let say, 100 photons were used, 100 electrons emitted, total electrical energy produced should be 100(hf-W) = VIt, no? And since hf - W are different, VIt should be different and so I...

I know intensity does. But, as I said, since these two metals have different work functions, their electrons emitted should have different kinetic energy, considered all other things equal, thus different current, or not? (E = VIt, with V and t constant (assumed), the larger E is the larger I...

Homework Statement Given two photocells, using light sources with identical frequency and intensity, but with different metal anodes with different work functions. Which of the followings are correct: A. The stopping voltage will be identical in both cells B. The current will be...
