Uninterruptible power system (UPS) has to be connected to the network by.
a) series to feed electrical power at normal time
b) parallel to feed electrical power at normal time
c) series to feed electrical power at critical time
d) parallel to feed electrical power at critical time
Homework Answers
A simple UPS connection circuit,
As we can see the UPS is connected in series with the supply. At normal time, UPS will bypass the mains line to load and if needed then charges the battery. At critical time, it will deliver power from the battery to load.
a) series to feed electrical power at normal time : This option is wrong as at normal time, UPS will bypass the mains line to load and if needed then charges the battery.
b) parallel to feed electrical power at normal time: UPS generally connected in series with the supply
c) series to feed electrical power at critical time: This option is right. At critical time, it will deliver power from the battery to load.
d) parallel to feed electrical power at critical time: UPS generally connected in series with the supply

(UPS Battery) On January 1, 2015, you bought a backup battery for your office uninterruptible power supply (UPS) system. In each of the next three years, the battery can fail and a new battery needs to be bought (if you want to keep using the UPS system). The maximum lifespan of the battery is four years; i.e., the battery must be replaced after four years. Due to chemical properties, the probability of the battery failure is fixed at 20% in...

A resistor R1 consumes electrical power P1 when connected to an emf E. When resistor R2 is connected to the same emf, it consumes electrical power P2. A) In terms of P1 and P2, what is the total electrical power consumed when they are both connected to this emf source in parallel? In solving this problem, you will want to use an expression for the resistances in terms of the power consumed by each when connected to the emf alone. B) ...
