Series Circuits

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end in a single path for the current to flow.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases as more resistors are added in series.

Front

How do you calculate the total resistance in a series circuit?

Back

The total resistance (R_total) is the sum of all individual resistances: R_total = R1 + R2 + R3 + ...

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): V = I * R.

Front

What is the formula to calculate voltage in a series circuit?

Back

Voltage (V) can be calculated using the formula: V = I * R_total, where I is the current and R_total is the total resistance.

Front

What is the relationship between current and voltage in a series circuit?

Back

In a series circuit, the current remains the same through all components, while the voltage is divided among the components.

Front

If the current is 1A and the resistance of a resistor is 3Ω, what is the voltage across that resistor?

Back

Using Ohm's Law, V = I * R = 1A * 3Ω = 3V.

Front

What is the definition of current?

Back

Current is the rate of flow of electric charge, measured in Amperes (A).

Front

What is the unit of resistance?

Back

The unit of resistance is the Ohm (Ω).

Front

How do you find the voltage drop across a resistor in a series circuit?

Back

The voltage drop across a resistor can be found using Ohm's Law: V_drop = I * R, where I is the current through the resistor and R is its resistance.
