จากรูปที่ 3.1.5 (ข) เป็นวิธีการหาค่

Figure 3.1.5 (b) is a method for determining the power output. Using the electrical voltage of
.A variac and measure the electrical current (i) of amp meter, which in this experiment to a value equal to 120 watts of power is how to adjust the voltage of the power of a variac and measure the electrical current from the amp meter.We must bring the electrical voltage (v), we have to adjust the voltage multiplied indefinitely. Until we have power as you want
.

From the image. 3.1.5 (b) is how to find the value of electrical power by means of electrical voltage adjustment from
.A Variac, power measurement (I) from an Amp meter in this experiment requires electrical power equal to 120 w how to adjust the voltage from electrical adjustments from a Variac, power measurement made from the Amp meter. We need to bring up the electrical supply voltage (V) that we have to multiply the value of electricity going until we get electrical power as required check
.

From figure 3.1 .5 (b) is a way to find the power supply using the method of adjusting the electrical voltage
The Variac and measure electrical current (I) from Amp meter in which the experiment was setup to power equal to 120 watts How to adjust the settings is to start from the electrical voltage from the Variac, and make the measurement Current meter from AmpWe will have to take up the electric voltage (V) that we have to adjust to current multiplied by the value until we have the power to be the
