When resistors are placed in parallel, the voltage across one resistor is (more/less/the same) than the voltage of the battery and the current going through the battery is (more/less/the same) than the current through a simple circuit. Therefore, the overall resistance of a circuit where resistors are placed in parallel is (higher/lower/the same) than the overall resistance of a simple circuit.

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
