Why is the experiment started with an initial load rather than starting at zero load?

horsena [70]

Answer: The answer would depend on the experiment but in most cases zero load is not used to ensure that there is no overflow of current.

Explanation: The internal resistance of any typical wire is minute compared to the resistive components that you are likely to utilize in any given experiment. Using I=V/R (Ohms law) , if the resistance is zero then the current that will flow through the wire would be much too high, causing the wire to burn out. The level of currents that the wire can tolerate are provided by the manufacturers. If you exceed those limits, than the wire will surely get permanently damaged. If you have no load at all than this will be known as a short circuit and might damage the source as well. If you have other components in the circuit than the overflow of current might in effect damage them too. This could also damage the bread board if you are using one.

Clear Lake has a surface area of 70 ha. In April the inflow of the lake was 1.5 m3/sec. A dam regulated the outflow of the lake

svetoff [14.1K]

Answer:

The estimated evaporation is 51340 cubic meters.

Explanation:

Let suppose that precipitation is very small in comparison with depth of the Clear Lake. The monthly change in the volume of the lake ( $\Delta V$ ), in cubic meters, is estimated by the following formula:

$\Delta V = A\cdot \Delta z + (\dot V_{in}-\dot V_{out})\cdot \Delta t -V_{evap}$ (1)

Where:

$A$ - Surface area of the lake, in square meters.

$\Delta z$ - Water precipitation, in meters.

$\dot V_{in}$ - Average water inflow, in cubic meters per second.

$\dot V_{out}$ - Average water outflow, in cubic meters per second.

$\Delta t$ - Monthly time, in seconds.

$V_{evap}$ - Evaporation, in cubic meters.

If we know that $A = 700000\,m^{2}$ , $\Delta z = 0.0762\,m$ , $\dot V_{in} = 1.5\,\frac{m^{3}}{s}$ , $\dot V_{out} = 1.25\,\frac{m^{3}}{s}$ , $\Delta t = 2.592\times 10^{6}\,s$ and $\Delta V = 650000\,m^{3}$ , then the estimated evaporation is:

$650000 = 701340-V_{evap}$ (2)

$V_{evap} = 51340\,m^{3}$

The estimated evaporation is 51340 cubic meters.
