What is constant in a series circuit?

Back

Current (measured in amps) is constant in a series circuit.

Front

How does the current in each resistor compare in a series circuit?

Back

In a series circuit, the current is the same through all resistors: I₃ = I₂ = I₁.

Front

What happens to the equivalent resistance in a series circuit?

Back

The equivalent resistance of a series circuit is larger than any individual resistance.

Front

What is constant in a parallel circuit?

Back

Voltage (measured in volts) is constant in a parallel circuit.

Front

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

Back

Total resistance (R_total) in a parallel circuit is calculated using: 1/R_total = 1/R₁ + 1/R₂ + 1/R₃ + ...

Front

What is Ohm's Law?

Back

Ohm's Law states that V = I × R, where V is voltage, I is current, and R is resistance.

Front

What is the effect of adding more resistors in series?

Back

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

Front

What is the effect of adding more resistors in parallel?

Back

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

Front

What is a short circuit?

Back

A short circuit occurs when there is a low-resistance connection between two points in a circuit, causing excessive current flow.
