A high-intensity portable lantern is powered by several batteries that are connected in series. The lantern’s bulb uses 86 W of power, while the current in the lantern is 3.0 A. Assuming that there is no power loss in the circuit, what is the total voltage of the batteries?

Answer 1

28.6666666667 or 29

Step-by-step explanation:

the formula for voltage (if power is involved)

V = P/i

86 ÷ 3

28.6666666667

if you want your can round to get a more simple answer

29
