Ohm's Law and Circuits

What is the current of a series circuit with a total resistance of 10 ohms and a voltage of 110 V

• 0.09

• 11.0

• 1100.0

• 10.0

What would you need to do to the voltage if you wanted to increase the current in a series circuit?

• Increase

• Greater

• Decrease

• Smaller

A panini press with a resistance of 20.6 ohms is plugged into a 134 V power source. After 17 minutes, what is the power used by the circuit?

• 14818.05825

• 889083.4951

• 871.6504854

• 110.5825243

What is the unit of current?

• volts (V)

• amps (A)

• ohms (Ω)

• joules (J)

What is the difference in finding total resistance in a series circuit vs. in a Parallel circuit?

• No Difference

• For series use inverse equation, for parallel add resistances up.

• For series add up resistances, for parallel add up resistances

• For series add up resistances, for parallel use inverse equation

When to use the P=I²R formula

• Never

• If the question only gives you current and resistance

• If the question only gives you voltage

• Always
