Front

What is the behavior of current in a series circuit?

Back

The current stays the same throughout the circuit.

Front

What happens to current when resistance increases?

Back

As resistance increases, current decreases.

Front

How many volts does one cell of a standard 12 Volt automotive battery provide?

Back

2.1 volts.

Front

What does it mean to test voltage drop across a load?

Back

You are measuring the difference in electrical potential across the load.

Front

What happens to the brightness of bulbs in a parallel circuit when another bulb is added?

Back

Each bulb stays the same brightness.

Front

Define voltage in the context of electrical circuits.

Back

Voltage is the electrical potential difference between two points in a circuit.

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

The total resistance increases, leading to a decrease in current.

Front

What is the effect of adding more resistors in parallel?

Back

The total resistance decreases, leading to an increase in current.

Front

Define electrical power in a circuit.

Back

Electrical power is the rate at which electrical energy is transferred by an electric circuit, calculated as P = V * I.
