Final Exam Review (PL) - Part 2

Front

As frequency increases, what happens to wavelength?

Back

It decreases.

Front

If a circuit has a resistance of 10 ohms and a current of 15 amperes, what is the voltage?

Back

150 volts.

Front

How much current is produced if a circuit has 80 volts of electricity and 18 ohms of resistance?

Back

4.4 amperes.

Front

If one bulb burns out in a parallel circuit, what happens to the others?

Back

They stay lit.

Front

Which wave has the highest frequency?

Back

Blue.

Front

What is the formula for Ohm's Law?

Back

Voltage (V) = Current (I) × Resistance (R).

Front

What is the relationship between frequency and wavelength in waves?

Back

They are inversely related; as frequency increases, wavelength decreases.

Front

What is the unit of electrical resistance?

Back

Ohm (Ω).

Front

What happens to total resistance in a parallel circuit when more resistors are added?

Back

Total resistance decreases.

Front

What is the frequency of a wave with a wavelength of 2 meters traveling at the speed of light (approximately 300,000,000 m/s)?

Back

Frequency = Speed / Wavelength = 150,000,000 Hz.
