Energy

What is solar insolation?

Solar insolation refers to how much sunlight is reaching the surface of the Earth.

What is defined as the flow of energy?

Current.

What is voltage?

Electromotive force or potential force, expressed in volts.

How is resistance defined?

Resistance is the measure of difficulty for energy to pass an electric current, measured in Ohm’s.

What is Ohm's Law?

Ohm's Law is represented by the equation V=IR and can be used to find voltage, current, or resistance.

How is power calculated?

Power is calculated using the formula P=VI and is measured in watts.

What is a photovoltaic cell?

A semiconductor that turns visible light into direct current, creating energy.

What does a turbine do?

A turbine produces constant energy, revolving when force from fluids causes it to rotate.

How do you calculate kilowatts from watts?

Kilowatts are calculated by dividing watts by 1,000.

What are the characteristics of a parallel circuit?

In a parallel circuit, resistors are connected in parallel; if one goes out, the others still work, and resistance is found by adding the reciprocals.

What happens in a series circuit when one resistor fails?

If one resistor goes out in a series circuit, all other resistors stop working due to the break in the circuit.

What is the formula for solving Ohm’s Law problems for voltage?

V=IR, and it is used when given resistance and current.

How do you find current using Ohm's Law?

Use I=V/R when given voltage and resistance.

How do you calculate resistance from voltage and current?

Use R=V/I when given the voltage and current.

What are the two types of renewable energy mentioned?

Solar energy and wind energy.

How does solar energy work?

Solar energy is harvested from the sun using solar panels set outside.

How is power generated by wind energy?

Large turbines are spun by the wind, generating the power.
