The stopping voltage where the current goes to zero is proportional to the KE of the electron.
Simply detecting a photocurrent doesn't tell you the electron's energy. You could try and find the photon energy where the PEE just barely works, but what if you don't have a continuously-tunable light source? (which most people don't). But a retarding potential is easily tuned.

The difference in voltage between the two sides of a device is called?

it means stopping bacteria from multiplying
What is the definition of stiff voltage divider?
Well, honey, a stiff voltage divider is basically a circuit that divides a voltage into two parts with minimal variation, even when there are changes in the load. It's like the Regina George of voltage dividers - it stays stable and doesn't let anything shake it up. So, if you want a reliable way to divide your voltage without any drama, a stiff voltage divider is the way to go.
Is the stopping voltage doubled or more than doubled if frequency of lightwave is doubled under the condition where intensity is constant?
More than doubled. The stopping voltage is the photon energy minus the work function: hv - W Doubling the photon energy creates a new stopping voltage of: 2 hv - W > 2 (hv - W)
Why stopping potential is negative?
The stopping potential is negative because it represents the work done by the stopping voltage to prevent the electrons from reaching the anode. This negative potential halts the kinetic energy of the electrons, causing them to return to the cathode.
What is the stopping potential formula used to calculate the minimum voltage required to stop the emission of electrons in a photoelectric experiment?
The stopping potential formula is V hf/e, where V is the stopping potential, h is the Planck constant, f is the frequency of the incident light, and e is the elementary charge. This formula is used to calculate the minimum voltage needed to stop the emission of electrons in a photoelectric experiment.
What means Low voltage release?
Low voltage release refers to the disconnection of a contactor and the stopping of the motor during power outage. This feature happens only with two-wire circuit.
What is the stopping potential equation used to calculate the minimum voltage required to stop photoelectrons emitted from a metal surface?
The stopping potential equation is V hf - W, where V is the stopping potential, h is the Planck constant, f is the frequency of the incident light, and W is the work function of the metal surface. This equation is used to calculate the minimum voltage needed to stop photoelectrons emitted from a metal surface.
How many feet does it take to stop at 55mph?
The stopping distance at 55 mph varies based on factors like vehicle type, road conditions, and braking efficiency. On average, it takes about stopping distance of stopping distance of 200-250 feet to come to a complete stop, which includes both the reaction distance (the distance traveled while the driver reacts) and the braking distance. If you consider a reaction time of about 1.5 seconds, this adds roughly 120 feet to the total stopping distance.
What are the uses of Fluke116?
The uses of a Fluke 116 is to measure temperature and micro-amps. It also has a special function for stopping false readings from a ghost voltage. There is also an in-built thermometer for HVAC appliances.
What is a sentence with the word stopping?
The stopping distance is increased on wet roads.There was no stopping the killer.The plane will be stopping at Dubai airport for refuelling.
Why is rise in voltage less during stopping of load than drop in voltage during starting?
The voltage drop during starting a load specially motor load is due to absence of back emf and due to high starting current drawn. In case of resistor/heaters, they are also wound like coil so they will also have some inductance and hence during starting, due to absence of back emf, a high current is drawn and hence the voltage drop. While stopping the load current drawn is smaller than the starting current. In the cases of motors and transformers their starting current is about 6 - 8 times the full load current and hence the above phenomenon asked in the question is observed.
What is stopping potential?
The stopping potential is the potential (energy/unit charge) or (Joules/Coulomb) that must be applied to stop the electrons from being ejected from the surface when the light is shone on it.
How do you say stopping in Spanish?
"to stop" is "parar"... if you want to say "I am stopping" it is "estoy parando." "we are stopping" is "estamos parando"
When was Stopping at Slowyear created?
Stopping at Slowyear was created in 1991.
