{'current': [0, 0, 0, 3], 'clectric bulb': [0, 0, 0, 1], 'electric charge': [0, 0, 1, 1], 'circuit': [0, 0, 1, 3], 'filament': [0, 0, 1, 7], 'amount': [1, 2, 4, 9], 'minutes': [0, 0, 1, 1]}

The amount of electric charge that flows through a circuit is determined by the current and the time that the current flows. In this question, the current is given as 0.5 A and the time is given as 20 minutes.

To find the charge, we can use the formula Q = I * t, where Q is the charge, I is the current, and t is the time.

Using this formula, we can calculate the charge as follows:

Q = 0.5 A * 20 minutes

Since the time is given in minutes, we should convert it to seconds for consistency. There are 60 seconds in 1 minute, so 20 minutes is equal to 20 * 60 = 1200 seconds.

Q = 0.5 A * 1200 seconds

Calculating the values, we get:

Q = 0.5 * 1200

Q = 600 C

Therefore, the amount of electric charge that flows through the circuit is 600 C.

Alert - correct answer should be 600 C
