أسئلة حول قانون أوم

What is Ohm's Law?

• Voltage is inversely proportional to current

• Voltage is directly proportional to current

• Resistance is inversely proportional to current

• Current is not affected by voltage or resistance

If the voltage across a constant resistance increases, then the current:

• Increases

• Decreases

• Remains constant

• Becomes zero

The unit used to measure electrical resistance is:

• Ampere (A)

• Ohm (Ω)

• Volt (V)

• Watt (W)

If the resistance is 10 ohms and the current is 2 amperes, then the voltage is:

• 5 Volts

• 10 Volts

• 20 Volts

• 0.5 Volts

If the resistance value in a circuit doubles while the voltage remains constant, then the current:

• Doubles

• Decreases to half

• Remains constant

• Becomes zero

When a voltage of 12 volts is applied to a resistance of 4 ohms, the current is:

• 0.5 Amperes

• 1 Ampere

• 2 Amperes

• 3 Amperes

Which of the following factors does not directly affect the electric current?

• Voltage

• Type of conductive material

• Ambient light intensity

• Electrical resistance

If you have a resistance of 6 ohms connected to a voltage source of 18 volts, what is the current flowing in the circuit?

• 0.33 Amperes

• 1 Ampere

• 2 Amperes

• 3 Amperes

In a circuit with a resistance of 8 ohms and a current of 4 amperes, the voltage applied to the circuit is:

• 12 Volts

• 16 Volts

• 24 Volts

• 32 Volts

If the voltage across a constant resistance is 10 volts and the current is 2 amperes, the resistance value is:

• 2 Ohms

• 5 Ohms

• 10 Ohms

• 20 Ohms
