Basic Elec (ohm's law, balanced, cable, impedance)

What is the formula for Ohm's Law?

• V = I x voltage

• I = V / R

• R = V x I

• V = I x current

What is "I" in the Ohm's Law formula?

• voltage

• resistance

• impedance

• current

According to Ohm's Law, if the current increases and the voltage remains the same, the resistance

• increases

• decreases

• remains the same

• disappear

Voltage = 6 v

Current = 3 amps

Resistance = ?

• 1 ohm

• 2 ohms

• 3 ohms

• 4 ohms

What is the unit of "R" in the Ohm's law formula?

• Reactance

• Resistance

• Ohm

• Ampere

If a light bulb is connected within a simple electrical circuit with a DC source (battery), it will act as the circuit's

• Current

• Voltage

• Resistance

• Reactance

Which one is considered as a conductor?

• rubber

• pillow

• bricks

• gold

A material that is 'electrically conductive' means

• it allows resistance to flow within itself

• it restricts the movements of electrons within itself

• it allows electrons to move within itself

• it restricts the movements of ants on itself

Is water considered as a conductor?

• Yes

• No

• Only when it is in a water bottle

• Only at night (because the temperature drops and the surrounding is dark)

Electrical Static happens when

• two insulator materials touching each other.

• two or more atoms combined in a molecular bond creating force of energy within a confined space resulting in the extraction of oxygen-based electrostatic particles.

• two insulated materials with different gender touches each other.

• two conductive materials with different potentials touching each other.
