• We will use the Wattmeter to find the average power supplied/absorbed by each component.
The following figure shows how to connect the Wattmeter to measure the average power
absorbed by the resistor. Note that the Wattmeter consists of a Voltmeter and an Ammeter. The
Voltmeter must be connected in parallel with the component and the Ammeter must be connected
in series with the component. You must pay attention to the polarity of the voltage across the
component as well as the direction of the current flowing through the component.

After searching the industrial site, you find an abundant amount of fuel to run the generators to keep you warm. You also find a memory card labelled “cure”, but your cell phone battery is dead. First things first, you will need to stay safe as the zombies continue to hunt you in your current location. The industrial site is surrounded by a metal chain-link fence. You decide you will electrify the fence to keep the zombies from scaling it. But the output voltage from the generators is not high enough to really deter them. You would like to apply around 10 kV to the fence (AC or DC, at that voltage it doesn’t really matter). You find a transformer that you can use but it only has a turn ratio of 10. You find some diodes and capacitors and construct the circuit shown in Figure 3 with the intention of hooking Vout to the fence.
