Coulomb

By Stacy King

A very large unit of electrical charge

These charges hold atoms together

Coulomb

Distance of charges affect on electrostatic force

q₁= 1st objects charge

q₂= 2nd objects charge

r = distance

k = 9.00 * 10¹⁰Nm²/C²

Coulomb's Law

Multiple Choice

If q₁ was doubled what would be the effect on the Force?

Doubled

Quadrupled

Half

1/4

Charges can be either positive or negative.

Multiple Choice

If r was doubled what would be the effect on the Force?

Doubled

Quadrupled

Half

1/4

I = Q/t

The current is equal to the charge divided by the time

Working with Charges

Multiple Choice

A current of 0.5 A flows in a circuit. Calculate the charge flowing through the circuit in one minute.

0.5 C

30 C

120 C

Multiple Choice

How much charge must pass by a point in 10 s for the current to be 0.50 A?

0,05C

5,0C

20C

2,0C

Multiple Choice

A charge of 48 C flows for 6s. What is the current?

8 A

288 A

8 V

288 V

The power to move electrical charges (the ability to do work)

Joules or J

Electrical Energy

Multiple Choice

10. A lamp begins with electrical energy when plugged in and turns into _________ energy when the light comes on.

Mechanical (PE + KE)

Kinetic

Radiant (Light)

Sound

Multiple Choice

Which statement best describes Electrical Energy?

Energy stored in an object due to its height above the earth.

Energy that is possessed by an object due to motion or position. This involves kinetic and potential energy.

Energy that is released during a reaction often in the form of heat.

Energy resulting from a flow of energy charge through a wire or other medium.

Energy is equal to Voltage times the charge

Electrical Energy Relationship

V= E/Q

The voltage is equal to the Energy divided by the charge

Working with Charges

Multiple Choice

If the Voltage of the Battery is 9V and the charge is 15C what is the work done (energy)?
