Circuits and Ohms Law 1st

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 can be expressed as V = I × R.

Front

What is the formula to calculate current?

Back

The formula to calculate current (I) is I = V / R, where V is voltage and R is resistance.

Front

What is the unit of current?

Back

The unit of current is Amperes (A).

Front

What is the unit of resistance?

Back

The unit of resistance is Ohms (Ω).

Front

What is the unit of voltage?

Back

The unit of voltage is Volts (V).

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow.

Front

What is an open circuit?

Back

An open circuit is a broken circuit where current cannot flow due to a gap or break in the path.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected across common points or junctions, providing multiple paths for current to flow.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the current flows through each component in turn.

Front

What is the relationship between voltage, current, and resistance?

Back

The relationship is defined by Ohm's Law: V = I × R.
