Two 1000-ohm resistors are connected in parallel across a 12-volt battery. What is the total current?

To find the total current, you can use Ohm's Law (I = E / R). First, determine the total resistance of the circuit. When two identical resistors are in parallel, their total resistance is half of one resistor's value. So, two 1000-ohm resistors in parallel equal 500 ohms total. Next, apply Ohm's Law using the total resistance and the source voltage: Current (I) = 12 volts / 500 ohms. This calculates to 0.024 amperes. To convert amperes to milliamperes, multiply by 1000. Therefore, 0.024 A equals 24 milliamperes. Alternatively, you could calculate the current for a single resistor (12V / 1000 ohms = 12 mA) and double it since there are two identical parallel paths.
