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

30 Coulombs

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  =  

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

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

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
