Electricity and Omhs Law

What is the formula equation for Ohm's Law?

• P=IxR

• P=IxE

• W=X+V

• W=A/V

The letter "I" corresponds with "Current", what does "E" correspond to?

(a)  

Watts are a measure of power where one watt = one ____ of energy

• gram

• electron

• joule

• meter

What is electricity?

• The flow of protons

• Power

• The flow of neutrons

• The flow of electrons

What kind of particles travel through a current?

(a)  

What does resistance measure?

• How much the material or device reduces electrical currents traveling through them

• How much the material or device amplifies electrical currents traveling through them

• How many electrons are stopped

• How much the material or device reduces potential/kinetic energy traveling through them

If "amps" are a measure of electrical current, what do ohms measure?

(a)  

What is the difference between a series circuit and a parallel circuit?

• Series circuit has 2 loops and a parallel circuit has more than 2

• Series circuits are more powerful than parallel circuits

• Series circuits contain one loop while parallel circuits contain 2 or more loops

• They are the same

A (a)   transforms mechanical energy into electrical energy typically by electromagnetic induction via Faraday's Law

In Faraday's Law, it states the faster the magnetic field changes...

• The greater the voltage will be

• The weaker the voltage will be

• The slower the current will be

• The faster the voltage will be
