Dear,

I would like to get help from you with this question! I need an answer with an explanation because I don't understand it.

Thank you in advance!!

With kind regards,

The light bulb has specs 14.0 V and 1.00 W. We assume the light bulb has constant resistance (independent of the current) and the emf of the battery remains constant. After these 8 hours the battery is disconnected from the light bulb and connected in this circuit for charging: R, e20 Pearon Education, inc The charger consists of a ideal voltage source with emf ɛ = 20.0 V (with no internal resistance) and a resistor Rị in series. (a) What is the minimum time that is needed to fully recharge the battery (with R1 = 0 2) (b) What should the resistance R1 be to fully recharge the battery in exactly 1 hour?
