Question

0.125 C of charge flow out of a

5.00 V battery in 6.30 s. How
much resistance is attached to the
battery?
(Hint: What is the definition of current?)
(Unit = Ohm)

Answer 1

Resistance = 252.53 Ohms

Step-by-step explanation:

Given the following data;

Charge = 0.125 C

Voltage = 5 V

Time = 6.3 seconds

To find the resistance;

First of all, we would determine the current flowing through the battery;

Quantity of charge, Q = current * time

0.125 = current * 6.3

Current = 0.125/6.3

Current = 0.0198 A

Next, we find the resistance;

Resistance = voltage/current

Resistance = 5/0.0198

Resistance = 252.53 Ohms
