e resistance of a copper wire is 20 Q. If a voltage of 10 V is a ross the wire, determine the current flowing through the wire an

A certain type of rechargeable battery can deliver a current of 0.6A for 400s, before its voltage drops and it needs to be recharged. Calculate: a) The total charge that battery can deliver before it needs to be recharged. b) The maximum time the battery could be used for without being recharged if the current through it were 0.7A. State your answer corrects to 2 decimal places.

A) find the equivalent resistance of the circuit  and B) the current through the battery simplify the cicruit. show all steps

A teapot with a surface area 9 325 cm2 is to be plated with silver. It is attached to the negative electrode & an electrolytic cell containing Silver nitrate (Ag+ NO3-). The cell is Powered by a 12.0- resistance battery and has a 의 son If the density & silver is 1.05 x 104 kg/m³, Over what time Interval does a 0-133-mm Jayer of Silver build up on the teapot?!! 의
