Max power transfer theorem and kirkchhoffs laws Lab Report

Max power transfer theorem and kirkchhoffs laws - Lab Report Example Irrespective of the high dissipated power because of the lower total resistance, it happens that the dissipated amount of power would be reduced. This paper reports on an experiment done to investigate the Maximum power transfer Theorem. A laboratory power supply was connected in series using a fixed 100 ohm resistor. A decade resistance box was connected across the simulated source of voltage to function as the variable resistor load, RL. The RL was temporarily removed and connected to the meter to measure the voltage across the 100 ohm resistor and the power supply. The power supply was adjusted until the voltmeter reads 1 v. The voltage setting was not adjusted from this point. The simulated voltage in the open circuit was found to be 1V. RL was reconnected. The current and the voltage was measured through connecting a voltmeter and ammeter as shown in diagram 1, for a number of values of resistance, RL, from zero to 200 ohms. The readings were recorded in table 1 under the results section of this report. The voltage was half the open circuit value at 200 ohm. This value was not expected. It is different from the theoretical value. This value was obtained as a result of experimental errors. The load current was half the short circuit value at 200 ohm. This value was not expected. It is different from the theoretical value. This value was obtained as a result of experimental errors. The load resistance for which power is dissipated in the load VLIL at the maximum is 200 ohms. This value was not expected. It is different from the theoretical value. This value was obtained as a result of experimental errors. The obtained result agrees with the maximum power transfer theorem, which argue that the dissipated power in the load would be maximum whenever the load is equal to the resistance source. The obtained results in the study were in agreement with the theorem of maximum power

Argument for emergency relief of disaster survivors Essay

Argument for emergency relief of disaster survivors - Essay Example However, the primary mindset that has traditionally governed the relief efforts made by the relief agencies is to extend medical assistance and supply basic necessities like food, medicines, clothing, drinking water and shelter to the disaster survivors. It would not be wrong to say that hitherto the relief efforts made by the relief agencies tended to focus on the external needs of the disaster survivors. The relief agencies till very recent times totally ignored the mental distress and the resultant mental health issues faced by the disaster survivors. For example it was only in 1989 that the Red Cross recognized the need for extending mental health services to the survivors in the disaster hit areas. Many government agencies and the policy makers deployed in important relief agencies believe that the visible and material needs and requirements of the people in the disaster hit areas should take precedence over the less obvious aspects such as the mental trauma and distress faced b y them. However, this approach towards disaster relief is utterly narrow and short sighted. Ignoring the mental health needs of the survivors in the disaster hit areas is indeed callous and in a way cruel. Disasters by their very nature happen to be instances that not only jeopardize the set way of life of the people in an area, but that also lead to the loss of the loved one’s and personal homes and possessions, acute physical injuries and physical trauma, and a total shattering of the social moral (McFarlane & Williams 1). Hence, a disaster is bound to cause much psychological and emotional distress to a significant proportion of the survivors in any impacted area. Hence, mental health services need to be an integral aspect of the relief extended to the survivors in the disaster hit areas so as to help the survivors cope up with the trauma and distress experienced by them, to
