Which is true of a parallel circuit?

The current is the same at each point in the parallel circuit.
The circuit has a single closed loop.
The potential difference across each lamp in a parallel circuit adds up to give the potential difference of a battery or cell.
The currents in each separate branch add up to the total current that leaves the cell.

Which sentence regarding the electrical resistance of components is correct?

The resistance of a light-dependent resistor increases as light level increases.
The resistance of a thermistor increases as temperature increases.
The resistance of a lamp increases as the current flowing through it increases.
A diode’s forward resistance is very high.

Which statement about the resistance of a component is true?

Two fixed resistors in parallel will have double the total resistance of a single resistor.
If two resistors are arranged in parallel, the total resistance is increased because the total current decreases but the potential difference is the same.
If two resistors are arranged in series, the total resistance is decreased because the current is greater but the potential difference is the same.
The total resistance is equal to the potential difference across it divided by the total current flowing through it.
