hello
my exam is tomorrow and I need helo in this problem please
Thank you

1-
Find the logic function of the RTL gate shown below. Assume V​
CC = 12 V, RC = 1 KΩ , RB = 10 KΩ, and that the Zener diodes drop 4.7 V when conducting.
NAND b) NOR c) AND d) NOT e) OR

2-

Find the output level (in V) that corresponds to LOW in the gate and the output that corresponds to HIGH.
a) 0.5 b) 0.7 c) 1.2 d) 0.2 e) 1 LOW
a) 12 b) 11.3 c) 6.6 d) 4.7 e) 15 HIGH

3-

Find the power drawn by the gate (in W) from the V​
CC power supply when only one input is high in the circuit.
a) 0.0118 b) 0.222 c) 0.142 d) 2.05 e) 0.0148

I need to understant I do not just want the answers..

Thank you
