Understanding Electric Charge and Current

This video provides a quick overview of electric charge, explaining it as the total current that flows over a period of time. Using a water analogy, charge is compared to the total amount of water flowing down a hill. The video introduces the equation for charge, which is the product of current and time, and demonstrates its application through examples involving a kettle and a phone charger. The video concludes with a call to action for viewers to like and subscribe.

What is the analogy used to explain electric charge in the video?

• Electric charge is like the height of a mountain.

• Electric charge is like the amount of water flowing through a river.

• Electric charge is like the brightness of a light bulb.

• Electric charge is like the speed of a car.

How is electric charge represented in equations?

• With the letter Q

• With the letter I

• With the letter C

• With the letter A

What is the unit of electric charge?

• Amps

• Coulombs

• Volts

• Watts

Which equation is used to calculate electric charge?

• Charge = Current x Time

• Charge = Resistance x Time

• Charge = Power x Time

• Charge = Voltage x Time

If a kettle draws a current of 12 amps for 50 seconds, how much charge passes through the wire?

• 50 Coulombs

• 120 Coulombs

• 60 Coulombs

• 600 Coulombs

What is the first step in solving the phone charger problem?

• Convert kilo coulombs to coulombs

• Multiply current by time

• Convert hours to seconds

• Divide charge by time

How many seconds are there in two hours?

• 3600 seconds

• 7200 seconds

• 5400 seconds

• 1800 seconds

What is the current if a phone charger transfers 43.2 kilo coulombs over two hours?

• 4 amps

• 5 amps

• 6 amps

• 7 amps

What is the rearranged equation to find current?

• I = Q x T

• I = Q + T

• I = Q / T

• I = T / Q
