Physics A Final

Front

What are magnetic patterns found on the ocean floor?

Back

They show alternating bands of normal and reversed polarity.

Front

What is the total current through a circuit if it measures 0.02 amps?

Back

0.02 amps is the total current.

Front

What happens to the current when a 3 volt battery is replaced with a 6 volt battery?

Back

The current doubles.

Front

What is an example of a conductor?

Back

A metal tube is an example of a conductor.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected alongside each other, so the current can split between them.

Front

What is the definition of electric current?

Back

Electric current is the flow of electric charge, measured in amperes (amps).

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the formula for calculating power in an electrical circuit?

Back

Power (P) = Voltage (V) x Current (I).

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected alongside each other.

Front

What is the unit of resistance?

Back

The unit of resistance is the ohm (Ω).
