Charge, current, time

• What is the definition of charge?

  Charge is a measure of total current over time
• How is charge represented in physics?

  Charge is represented by the letter q
• In what unit is charge measured?

  Charge is measured in coulombs
• What is the equation for calculating charge?

  Charge equals current multiplied by time
• If a kettle draws a current of 12 amps for 50 seconds, how much charge passes through the wire?

  600 coulombs
• How do you rearrange the charge equation to find current?

  Current equals charge divided by time
• How do you convert kilo coulombs to coulombs?

  Multiply by 1000
• How do you convert hours to seconds?

  Multiply hours by 3600
• If a phone charger transfers 43.2 kilo coulombs over 2 hours, what is the current?

  6 amps
• What is the relationship between charge, current, and time?

  • Charge (q) = Current (i) × Time (t)
  • Charge is total current over time
• What are the steps to calculate current from charge and time?

  1. Rearrange the equation: i = q / t
  2. Convert units if necessary
  3. Plug in values and calculate
• How does the water analogy explain charge and current?

  • Current: Rate of water flow
  • Charge: Total water flowed over time
• What is the definition of charge?

  Charge is a measure of total current over time
• How can charge be compared to water flow?

  Charge is like total water flowing down a hill
