Analyzing our results.
- Thevenin , Norton equivalent circuit
▶ Draw an equivalent circuit and confirm that isc = Veq / Req
▶ In table 2-1 experiment using 470[Ω] and 1[KΩ], we can calculated the Veq and Req.
=> ................................[1]
=> ................................[2]
Solving the upper two equations, we can get the value of the Veq & Req. and in this values we
can get the Isc ,too
∴Veq 6.104[V] & Req 382.9[Ω] & Isc 15.93[mA]
▶ In table 2-1 another experiments, we can confirm that Isc is equal to Veq / Req
=> ex) In experiment using 2[KΩ] , table [2-1]
Veq [V]



▶ The condition for maximum power delivery in the AC circuit is equal to the condition in the DC
: Just think in the phase circuit.... The value of the RL must be same the value of Rs
- The equilibrium bridge circuit
▶ What are the factors that effect the accracy in the experiment?
▶ The resistors must not be effected by the temperature in the lab and have accurate value.
▶ The conducting wire has lilttle resistance, so we have to be able to ignore that.
▶ Need for a electronic current indicator , we must not measure the value by eye
▶ The reason why we use the high sensitivity ammeter in this experiment
▶ In Wheatstone Bridge, if the current flows in a terminal connected to an ammeter,
the very large error might happen.
so we must check the current in the terminal connected to a ammeter very sensitive.
hence we must use the high sensitivity ammeter
▶ The reason why the resistor must be inserted in an ammeter.
▶ Of course, a little resistance exists in a ammeter , but that is too small so very large current
might flow through a wire connected to an ammeter
