Questions related to electrical engineering and digital electronics.

KCL (Kirchhoff's Current Law) states that the sum of currents entering a node is equal to the sum of currents leaving the node.
KVL (Kirchhoff's Voltage Law) states that the sum of voltage drops around a closed loop is equal to the applied voltage.
The voltage drop across the 5 ohm resistor is 3V.
The equivalent resistance of 4 meshes each having 3 resistances of 2 ohms is 6 ohms.
Microprocessor is a single chip CPU while microcontroller has a CPU, memory, and I/O peripherals on a single chip.
Flip-flops are digital circuits used to store binary data. Types include SR, D, JK, and T flip-flops.
Race around condition occurs when the inputs of a flip-flop change too quickly for the output to settle. It can be overcome by using clocked flip-flops.
T in T-flip-flop stands for toggle while D in D-flip-flop stands for data. T-flip-flops are used in counters and frequency dividers while D-flip-flops are used in registers and memory circuits.
Combinational circuits perform logic operations on inputs to produce outputs while sequential circuits use feedback to store information and produce outputs.
Practical applications of combinational circuits include adders, multiplexers, and demultiplexers while practical applications of sequential circuits include counters, shift registers, and memory circuits.

Accepted Answer

KCL and KVL
KCL (Kirchhoff’s Current Law):
Statement: The total current entering a node (junction) is equal to the total current leaving the node.

Formula: ΣI_in = ΣI_out

KVL (Kirchhoff’s Voltage Law):
Statement: The sum of all voltages around a closed loop is zero.

Formula: ΣV = 0 (around a loop)
