• True

• False

A circuit where there are several paths for the current to flow is a parallel circuit.

• True

• False

The total current in a parallel circuit is the sum of the current across the circuit.

• True

• False

Voltmeters have a very low internal resistance.

• True

• False

The total current in a series circuit is equal to the sum of individual currents in across each resistor.

• True

• False

The total resistance of parallel circuit is always less than the value of the lowest resistance.

• True

• False

Changing the value of one resistor in a series circuit changes the current through all other resistors in the circuit.

• True

• False

Changing the value of one resistor in a parallel circuit changes the current through all other resistors in the circuit.

• True

• False

The voltage drop in parallel circuit is the same across the circuit.

• True

• False
