Answers
Answer:
a) 20 Ω
b) 1 A
c) 10 V on each
d) 1/3 A through each
e) 10 W in R1, 3 1/3 W in the others
f) 20 W
Explanation:
The three 30 Ω resistors are in parallel with each other, so will have an equivalent resistance of (30 Ω)/3 = 10 Ω.
(a) The total circuit resistance is 10 Ω + 10 Ω = 20 Ω.
__
(b) All of the current supplied by the battery passes through R1. The current supplied by the battery is ...
I = V/R = (20 v)/(20 Ω) = 1 A
__
(c) The voltage drop on R1 is (1 A)(10 Ω) = 10 v. Subtracting that from the battery voltage gives the voltage drop on the other resistors:
20 v -10 v = 10 v . . . . drop on R2, R3, R4
__
(d) The current through resistors R2, R3, R4 is ...
I = V/R = (10 v)/(30 Ω) = 1/3 A
__
(e) Power can be computed several ways. Here, it may be easiest to use ...
P = VI
For R1, that is P1 = (10 v)(1 A) = 10 W
For R2-R4, that is P2-P4 = (10 v)(1/3 A) = 10/3 W = 3 1/3 W
__
(f) The total power dissipated is the total power supplied:
P = VI = (20 v)(1 A) = 20 W
Adding up the power in the resistors, we get ...
P = 10 W + 3·(10/3 W) = 20 W

Answers
The technician can reasonably assume that evaporator coil is frozen over.
An air-conditioning system makes a place cooler by absorbing heat from the
surrounding. This is usually done with the aid of the evaporator coil.
In situations whereby there are ice particles formed on the suction line at the
condensing unit then it means the air conditioning system is faulty and must
be turned off to prevent damage to other parts.

a technique you can use when dealing with persistent harassers of your server is called
Answers
A technique you can use when dealing with persistent harassers of your server is called "IP banning" or "IP blocking."
Since IP banning involves blocking the harasser's IP address, which is a unique numerical label assigned to each device connected to a network. By blocking their IP address, you prevent them from accessing your server or website.
The IP banning process generally works as Identifying the harasser: Before you can ban someone's IP address, you need to identify the individual responsible for the harassment.
Then Obtain the harasser's IP address: Once you have identified the harasser, you need to obtain their IP address. This information can be found in server logs or through various online tools that can track IP addresses.
Implement the ban: Once you have the harasser's IP address, you can proceed to ban it. This is typically done through server or website administration tools. The process may vary depending on the specific server software or platform you are using.
4. Test the ban: After implementing the ban, it is important to test whether it is effective. You can do this by attempting to access your server or website from a device using the banned IP address.
Therefore, it is recommended to use IP banning in conjunction with other security measures and to regularly review and update your ban list as necessary.
