What would be the total current draw of the circuit as shown in figure "A" of the illustration if the source voltage is 24 volts, the resistance for R1 is 12 ohms, the resistance for R2 is 24 ohms, and the resistance for R3 is 36 ohms? Illustration EL-0032

Question

Accepted Answer

Option D: 1.33 amperes. Series total resistance is the sum: 12 + 24 + 36 = 72 ohms. Applying Ohm's law with a 24-volt source yields total current I = V / Rt = 24 / 72 = 0.333 amperes, corresponding to 0.33 amperes.
