Imagine that you need to use a voltmeter to read the voltage drop across a load in a circuit. Which one of the following statements describes the correct way to connect
a voltmeter to the circuit?
O Connect the voltmeter in parallel with the load.
Connect one of the voltmeter's leads to the load, and the other lead to ground.
Connect the voltmeter in series with the load.
Connect one of the voltmeter's leads to the load, and the other lead to <br /> a
battery.

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
