19. A circuit contains four 100 S2 resistors connected in series. If you test the circuit with a digital VOM, you should read a total resistance value of
Α. 1,000 Ω.
Β. 250 Ω.
C. 100 Ω.
D. 400 2.

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
