Ohm’s Law

Define Ohm’s Law

• a law stating that electric current is proportional to voltage and inversely proportional to resistance.

• a law stating that electric current is proportional to resistance and inversely proportional to voltage.

According to Ohm's Law, current equals the voltage divided by the _________.

• Resistance

• Inductance

• Capacitance

• Power

• Conductance

If the current in an electrical circuit is constant, what will happen to the voltage if the resistance is increased?

• The voltage will decrease

• The voltage will increase

• The voltage will stay the same

What is the Voltage, V in the circuit shown?

• 6.5 V

• 26 V

• 0.15 V

If there are 40 Volts and 5 Amps running through an electrical circuit, what is the resistance of the circuit?

• 1 Ohm

• 2 Ohms

• 4 Ohms

• 6 Ohms

• 8 Ohms

The circuit with higher resistance will allow less charge to flow, meaning the circuit with higher resistance has less current flowing through it.

• True

• False

10) If you increase the size of the resistor and keep the voltage the same, what will happen to the current?

• The current will decrease

• The current will increase

• The current will stay the same
