GR7 4THQTR IA OHMS LAW PART 2

What does Ohm's law relate to in a circuit?

• Power and energy

• Capacitance and inductance

• Voltage, current, and resistance

• Frequency and wavelength

If you know the voltage and resistance, how can you find the current?

• Subtract resistance from voltage

• Divide voltage by resistance

• Add voltage and resistance

• Multiply voltage by resistance

Which form of Ohm's law would you use to find resistance?

• I = V/R

• R = V/I

• V = I + R

• V = IR

What happens to the balance if you increase the voltage in a circuit?

• The current must decrease

• The resistance must increase

• The current or resistance must change

• Nothing changes

In the grocery analogy, what does the scale represent?

• The weight of groceries

• The number of customers

• The balance of voltage, current, and resistance

• The price of goods
