(Electricity 05) Ohm's law and Electrical Energy Consumption

Question 1

What is Ohm’s law?

Answer 1

V = I x R

Question 2

What is the equation for voltage?

Answer 2

V = I x R

Question 3

What is the equation for current?

Answer 3

I = V/R

Question 4

What is the equation for resistance?

Answer 4

R = V/I

Question 5

What is voltage?

Answer 5

Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current).

Voltage is pressure that pushes the current.

Question 6

What is current?

Answer 6

Current is the rate at which electrons flow past a point in a complete electrical circuit.

Question 7

What is resistance?

Answer 7

Resistance is a measure of the opposition to the flow of current in an electrical circuit.

counteracts the flow of current.

Question 8

What is a kilowatt-hour? (kW)

Answer 8

Kilowatt that is used in one hour.

Question 9

How much watts is one kilowatt?

Answer 9

1000

Question 10

How do you calculate the cost of electricity rates? (Ex. how long you used the washing machine)

Answer 10

Cost = Number of kWh x Cost per kWh
