Resistance of voltmeter experiment. Graph between r and 1/v

Resistance of voltmeter experiment. Graph between r and 1/v

In this video, i have explained how to find resistance of voltmeter by graph. In the experiment, i have made the circuit according to the circuit diagram, We have high resistance box, voltmeter and the battery which are connected in series combination. We took the observation and noted different values from high resistance box and their corresponding readings of voltmeter. Afterword's, calculate the reciprocal of each value of then voltage from voltmeter. Then i have plotted the graph between resistance and 1/V .

The conversion of galvanometer into voltmeter experiment

The conversion of galvanometer into voltmeter experiment

In this video we will explain how the galvanometer can be converted into voltmeter. Conversion of galvanometer into voltmeter experiment carried out through three steps. In first step we find the resistance of #Weston type galvanometer by half deflection method. We use high resistance box and # fractional resistance box for this purpose. In second step, the galvanometer is attached to resistance in series combination, and we find the load resistance that is required to convert the galvanometer into voltmeter. In the last step, we verify how converted voltmeter measures the voltage with the counter verification made from a standard voltmeter connected in parallel to the converted voltmeter. we found that there is no difference between the standard voltmeter reading and to that of converted one. You'll also be able to carry out this experiment yourself, so you can learn for yourself!

Variation of photocurrent with intensity of light II photoelectric effect

Variation of photocurrent with intensity of light II photoelectric effect

In this video, we'll be discussing the photoelectric effect. This is a phenomenon where the intensity of light causes a change in the amount of electricity that is generated in a certain area of a material. The photoelectric effect is one of the most important concepts in physics, and understanding it can help you understand a lot of different phenomena in the world. In this video, we'll be discussing the variation of photoelectric current with intensity of light, and how it can help you understand a lot of different phenomena in physics! In this video, the #photoelectric effect has been explained. The intensity of light increased through certain distance and it made incident on photocell. The photoelectrons are ejected from the photocell. Thus the photoelectric current is detected by the fixed coil galvanometer. This phenomenon is based on the Einstein's explanation of photo electric effect. Photoelectric Effect| Experiment.

The Labor Party says it will scrap educational cost charges in England, which were expanded to more than £9,000 a year under the coalition government.

The gathering additionally guarantees to reintroduce support recompenses, constrain class sizes and stretch out free childcare to 30 hours for each of the two-year-olds.

The Conservatives portrayed the declaration as "irrational".
The Labor Party is proposing to submit an additional £25.3bn for
