What is the relationship between voltage, current, and resistance according to Ohm's Law?

• The relationship between voltage, current, and resistance is defined by Ohm's Law.

• Resistance has no effect on the relationship between voltage and current

• Voltage and current are inversely proportional to each other

• The relationship between voltage, current, and resistance is determined by Newton's Law

What happens to the current in a circuit if the voltage is doubled while the resistance remains the same?

• The current will be halved

• The current will remain the same

• The current will double

• The current will quadruple

Explain the significance of Ohm's Law in circuit design.

• It measures the temperature of a circuit

• It determines the color coding of resistors

• It calculates the speed of electrons in a circuit

• It relates voltage, current, and resistance in a circuit
