Front

What does not affect the resistance in a wire?

Back

Insulation does not affect the resistance in a wire.

Front

What is the measurement performed in the image?

Back

Rt is the measurement performed in the image.

Front

What happens to the current in a series circuit?

Back

The current stays the same in a series circuit.

Front

What does Current times Resistance equal (I X R)?

Back

Voltage is equal to Current times Resistance (I X R).

Front

What type of electricity is derived from a battery?

Back

Direct Current is derived from a battery.

Front

What is the formula for calculating resistance in a wire?

Back

Resistance (R) = Voltage (V) / Current (I).

Front

What is Ohm's Law?

Back

Ohm's Law states that Voltage (V) = Current (I) x Resistance (R).

Front

What is the unit of resistance?

Back

The unit of resistance is Ohm (Ω).

Front

What happens to voltage in a parallel circuit?

Back

In a parallel circuit, the voltage across each branch is the same.

Front

What is the difference between alternating current (AC) and direct current (DC)?

Back

AC changes direction periodically, while DC flows in one direction.
