Battery line voltage drop

Step #6: To find the voltage drop subtract your answer found in step #5 (0.3618) from the starting voltage of 24 volts. 24 - 0.3618 = 23.6382 volts. Step #7: Sometimes you may be asked to know the voltage drop percentage. To find this, take the voltage drop (0.3618 volts) divided by 24 volts and multiply it by 100.
