Circuits and Ohms Law

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where the same current flows through all components, and there is only one path for the current to take.

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 expressed as V = I × R.

Front

What unit is used to measure current?

Back

Amperes (A) or simply Amps.

Front

What unit is used to measure resistance?

Back

Ohms (Ω).

Front

What is the formula to calculate resistance?

Back

Resistance (R) can be calculated using the formula R = V / I, where V is voltage and I is current.

Front

What happens to the current in a series circuit if one component fails?

Back

If one component fails in a series circuit, the entire circuit is broken, and the current stops flowing.

Front

What is the unit of measurement for voltage?

Back

Volts (V).

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where there are multiple paths for the current to flow, and the voltage across each component is the same.

Front

How does adding more resistors in series affect the total resistance?

Back

Adding more resistors in series increases the total resistance of the circuit.

Front

How does adding more resistors in parallel affect the total resistance?

Back

Adding more resistors in parallel decreases the total resistance of the circuit.
