Question

A 3.00 V battery is connected to the ends of a length

of constantan wire of resistance 12.1 Ohms. Calculate the
charge that flows through the wire in 60 s. Write down
any equations you use. Give your answer to three
significant figures.
Charge=
______C [5 marks]

Answer 1

Answer: The charge that flows through the wire in 60 s is 14.87 C.

Explanation: The charge that flows through the wire in 60 s can be calculated using the formula:

Charge = Current x Time

The current can be calculated using Ohm’s law:

Current = Voltage / Resistance

Substituting the given values:

Current = 3.00 V / 12.1 Ohms = 0.2479 A

Charge = 0.2479 A x 60 s = 14.87 C

Hope this helps, and have a great day! =)
