Understanding OHm's Law

What does OHm's Law state?

• Ohm's Law states that resistance is equal to voltage plus current.

• Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.

• Ohm's Law states that current is equal to voltage divided by resistance.

• Ohm's Law states that voltage is equal to current minus resistance.

What is the formula for OHm's Law?

• I = V + R

• V = R / I

• R = V - I

• V = I * R

What does 'V' represent in OHm's Law?

• Voltage

• Resistance

• Power

• Current

What does 'I' represent in OHm's Law?

• Voltage

• Current

• Resistance

• Power

What does 'R' represent in OHm's Law?

• Voltage

• Current

• Resistance

• Power

If the voltage is 10 volts and the resistance is 2 ohms, what is the current?

• 2 amps

• 5 amps

• 1 amp

• 10 amps

If the current is 3 amps and the resistance is 5 ohms, what is the voltage?

• 15 volts

• 10 volts

• 5 volts

• 20 volts

How does increasing resistance affect current, according to OHm's Law?

• Increasing resistance has no effect on current.

• Increasing resistance increases current.

• Increasing resistance stabilizes current.

• Increasing resistance decreases current.

What happens to voltage if current increases while resistance remains constant?

• Voltage remains the same regardless of changes in current or resistance.

• Voltage becomes zero if current increases while resistance is constant.

• Voltage increases if current increases while resistance remains constant.

• Voltage decreases if current increases while resistance remains constant.

Can OHm's Law be applied to AC circuits? Why or why not?

• Impedance is not relevant in AC circuits.

• Yes, Ohm's Law can be applied to AC circuits using impedance.

• AC circuits do not have resistance.

• Ohm's Law only applies to DC circuits.
