Ohm's Law Circuits

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.

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).

What happens to current in a series circuit?

Back

In a series circuit, the same current flows through all components.

Front

What happens to voltage in a series circuit?

Back

In a series circuit, the total voltage is the sum of the voltages across each component.

Front

How do you calculate total resistance in a series circuit?

Back

Total resistance (R_total) in a series circuit is the sum of all individual resistances: R_total = R1 + R2 + R3 + ...

Front

How do you calculate total current in a circuit?

Back

Total current (I) can be calculated using Ohm's Law: I = V / R, where V is the total voltage and R is the total resistance.

Front

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

Back

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

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, resulting in multiple paths for current to flow.
