first the total resistance must be taken into account
the total resistance is equal to
3 ohm + 3 ohm + 3 ohm + 3 ohm = 12 ohm.
voltage = 1.5
therefore the current drawn is = 1.5/12 = .125 A
we know that current = power / voltage
power = current * voltage = .125 * 1.5 = .1875 watt
therefore the power that is dissipated = .1875
therefore the correct answer is option 2
plz mark as brainliest
