Resistor Circuits | MCQs

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
