Ohms Law Questionaire

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. It is usually expressed as V = I * R.

Front

What is the formula to calculate current when power and voltage are known?

Back

The formula to calculate current (I) when power (P) and voltage (E) are known is I = P / E.

Front

What is the third standard metric prefix?

Back

The third standard metric prefix is 'kilo', which represents a factor of 1,000.

Front

What does the prefix 'giga' indicate in engineering notation?

Back

The prefix 'giga' indicates multiplication by 1,000,000,000 (10^9).

Front

What is the unit of electric potential?

Back

The unit of electric potential is the volt (V).

Front

What is the relationship between the speed of AC through a conductor and the speed of light?

Back

The velocity of AC through a conductor is less than the speed of light.

Front

What is the unit of electrical resistance?

Back

The unit of electrical resistance is the ohm (Ω).

Front

What is the unit of power in an electrical circuit?

Back

The unit of power in an electrical circuit is the watt (W).

Front

How do you calculate power in an electrical circuit?

Back

Power (P) can be calculated using the formula P = V * I, where V is voltage and I is current.

Front

What does the term 'ampere' refer to?

Back

The ampere (A) is the unit of electric current, defined as one coulomb of charge passing through a point in a circuit per second.
