Question

Five coulombs of charge flow past a point in 0.5 seconds. How many amperes of current are flowing?

a) 5 A
b) 2.5 A
c) 10 A
d) 1 A

Answer 1

The current flowing when five coulombs of charge pass a point in 0.5 seconds is 10 amperes.

Step-by-step explanation:

Five coulombs of charge flow past a point in 0.5 seconds.

The current flowing can be calculated using the relationship between charge (Q), current (I), and time (t), which is given by the formula I = Q / t.

Plugging in the given values, we get I = 5 C / 0.5 s, which equals 10 amperes of current. Therefore, the correct answer is 10 A.

To give an example with a related concept, if a battery is connected to a bulb with a current of 2.5 A, the amount of charge that would flow through the circuit in a time of 0.5 seconds is found by Q = I * t. So Q = 2.5 A * 0.5 s, which is 1.25 C.
