Electrical Theory 1

Front

What is the total resistance in a parallel circuit compared to the smallest resistor?

Back

The total resistance is smaller than the smallest resistor.

Front

How many paths are there for current to flow in a parallel circuit?

Back

There is more than one path for current to flow.

Front

In a series circuit, what remains constant?

Back

Amperage stays the same.

Front

Calculate the total resistance of a parallel circuit with a 5 ohm and a 20 ohm resistor.

Back

The total resistance is 4 Ohms.

Front

What is electrical pressure measured in?

Back

Electrical pressure is measured in Volts.

Front

Define a series circuit.

Back

A series circuit is a circuit where components are connected end-to-end, so the same current flows through all components.

Front

Define a parallel circuit.

Back

A parallel circuit is a circuit where components are connected across the same voltage source, providing multiple paths for current.

Front

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

Back

The total resistance decreases.

Front

What is the formula for calculating total resistance in a parallel circuit?

Back

1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

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

Back

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