Ohm's Law

Ohm's Law is the fundamental relationship between voltage, current, and resistance:

* V = I * R

Where:

* V is voltage (in volts)

* I is current (in amperes, or amps)

* R is resistance (in ohms)

Calculation

1. Identify the values:

* V = 12 VDC

* R = 1000 ohms (1K-ohm)

2. Rearrange the formula to solve for current (I):

* I = V / R

3. Substitute the values and calculate:

* I = 12 V / 1000 ohms

* I = 0.012 amps

Answer:

The current flowing in the circuit will be 0.012 amps or 12 milliamps (mA).
