Question

The current through a lightbulb is 0.5 amps. How much charge passes through the lightbulb each minute?

Question 6 options:

2 Coulombs


30 Coulombs


120 Volts


2 Volts


120 Coulombs


30 Volts

Answer 1

30 Coulombs

Step-by-step explanation:

Given parameters:

Current = 0.5A

Time = 1min = 60s

Unknown:

Charge that must pass through = ?

Solution:

The current in the circuit can be expressed using the equation below;

I =
`(q)/(t)`

I is the current, q is the charge and t is the time taken

q = current x time = 0.5 x 60 = 30 coulombs
