Why shouldn't an electrical component ever be placed in a parallel circuit if it has a voltage rating less than the source voltage?

Correct Answer

verified

In a parallel circuit, each resistor is placed directly across the main source of voltage. This causes each resistor to operate at the same voltage as the source. Therefore, each electrical component in a parallel circuit must have a voltage rating greater than the voltage source.

Question 3

Short Answer

Review LaterAdd Note

In a parallel circuit, each resistor operates at the same voltage as the ____________________.

Adding parallel branches to a circuit increases the total resistance.

If you can apply a known source voltage, but you do not know the resistance of the individual resistors in a parallel circuit, how can you determine the total resistance in the circuit?

In a parallel circuit, the total resistance will always be less than the smallest R in the circuit when two or more resistors are present.

The total current in a parallel circuit is equal to the ____________________ of the currents in the separate components.

A(n) ____________________ circuit has more than one path for current.

It is acceptable to place an electrical component in a parallel circuit if it has a voltage rating less than the source voltage.

The components in a parallel circuit operate independently of one another.
