Final answer:
When the UPSs (Uninterruptible Power Supplies) are unplugged from an electronic system, an interruption in power supply occurs and an increase in current may be observed. Hence, b) and c) are correct.
Step-by-step explanation:
When the UPSs (Uninterruptible Power Supplies) are unplugged, there are a few changes that are evident in an electronic system:
- Interruption in power supply: Unplugging the UPSs disrupts the power supply, causing a temporary loss of electricity to the electronic system.
- Increase in current: Without the UPSs to regulate the power, the current flowing through the electronic system may increase.
