Spring ACP Review Electricity Warm-up

What letter represents Current?

• A
• I
• R
• E

What is resistance measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

What is current measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

How do you calculate voltage?

• Current X Resistance
• Resistance ÷ Current
• Current ÷ Resistance
• Measure it with a ruler

How do you calculate current

• Resistance X Voltage
• Voltage X Resistance
• Resistance ÷ Voltage
• Voltage ÷ Resistance

What is Resistance?

• The flow of electrons
• Electric potential difference
• A battery
• The ability to reduce the flow of electrons

What is the correct definition of current?

• The rate of electron flow
• the opposition presented to the current by a material or device
• the rate at which a device can convert electrical energy into another form of energy
• the potential difference or electromotive force, it represents the amount of work that moving an electric charge between two points would take

What is the correct definition of voltage?

• The rate of electron flow

• the opposition presented to the current by a material or device

• the rate at which a device can convert electrical energy inro another form of energy

• the potential difference or electromotive force, it represents the amount of work it would take to move an electric charge between two points

The Law of Charges mandates that like charges

• attract each other

• repel each other

• don't interact with each other

What are Conductors?

• A material that allows electric charge to move through it. Usually the charge is carried by electrons, and the conductor is a metal.

• A material that does not easily allow electric charge (or heat, electricity, light, sound) to pass through it. Air, cloth and rubber are good electrical conductors.
