Explanation

To solve this problem, we need to find the total current (I) drawn from the 220 V source.

First, let's find the current through one resistor:

I1 = V/R = 220 V / 68 ohms = 3.24 A (using Ohm's Law)

Since all resistors are identical and connected in parallel, the current through each resistor is the same:

I1 = I2 = I3 = I4 = 3.24 A

Now, we can find the total current (I) by adding the currents through each resistor:

I = I1 + I2 + I3 + I4 = 3.24 A + 3.24 A + 3.24 A + 3.24 A = 12.96 A ≈ 12.94 A

So, the correct answer is: 12.94 A

Explanation

The output of an OR gate will be high when any of the inputs is high.

An OR gate outputs a high signal if at least one input is high.

Explanation

A network containing one or more sources of EMF is known as an Active Network.

Active networks include elements like batteries or generators that provide energy to the circuit.

Explanation

The LTI (Linear Time-Invariant) system is characterized by its impulse response.

This response fully describes the system's behavior and can be used to determine the system's response to any input.

Explanation

The output of an XNOR (Exclusive NOR) gate will be high when the input logic levels are the same.

XNOR gates output a high signal when both inputs are either both high or both low.

Explanation

Two batteries with unequal EMF can be connected only in series.

Connecting them in parallel can cause excessive current flow and potential damage.

Explanation

Polygamy is neither mandatory nor encouraged.

It is allowed in some cultures or religions but is not actively promoted or required.

Explanation

Explanation

An inverter converts DC to AC.

It changes direct current (DC) into alternating current (AC) for applications requiring AC power.

Explanation

Microcontrollers usually integrate all essential components but may not have a separate Memory Management Unit (MMU).

The MMU is often found in more complex systems, not typically in basic microcontrollers.
